Viewing AWS Used Resources and Costs for Finance Team: Guide to Exporting PDF Reports

usXCloudSec — Thu, 11 Dec 2025 15:11:31 +0000

In almost every organization I’ve worked with, I’ve noticed a common pattern: finance teams struggle to interpret AWS invoices. Unlike traditional IT billing — where expenses are predictable and appear as simple line items AWS bills are dynamic, usage-based, and highly granular.

Finance departments are accustomed to concise, one-page summaries that clearly show:

What was used
Who used it
Why it was used
What it cost

AWS, on the other hand, generates billing data that can span thousands of line items, covering services, usage types, commitments, credits, taxes, and more. This creates a gap:
➡ Finance wants clarity and simplicity
➡ AWS provides raw, complex consumption data

We can get UsageCost Report/Bill by following steps:

Step 1: Login to AWS console and search for Billing and Cost Management and click on it.

Step 2: After opening Billing and Cost Management look for bills and click on it.

Step 3: After doing that we can Download bill in CSV format, we can print, and we can select date/year of the bills from console. we can see the charges by service, charges by account (if it is organization account), we can download invoices, see saving(if we have AWS credits), and see taxes by services from bills Section of console.

How we can Present AWS Billing to Finance Teams (FinOps Best Practice)

As an AWS FinOps professional, I always follow a structured approach:

✅ Step 1 – Review the detailed spend in the console
(Services → Usage Types → Regions → Accounts)

✅ Step 2 – Identify key cost drivers
Top services, teams, and resources.

✅ Step 3 – Map technical usage to business context
Tag or categorize costs meaningfully.

✅ Step 4 – Convert findings into a finance-friendly summary
Usually 1–2 pages with:

Total cost
Cost variance from last month
Root cause of increases
Optimizations done
Recommendations

✅ Step 5 – Provide supporting PDF/CSV for transparency
Finance receives both a summary and the detailed evidence.

Conclusion:

Finance teams prefer a simple, one-page AWS cost summary—but AWS does not naturally provide billing that way. As FinOps professionals, it will be our responsibility to:

Analyze the raw, detailed bill in the AWS console
Understand cost drivers and usage patterns
Translate complex cloud spend into business language
Present clear, concise, accurate financial reports

By reviewing the AWS billing console thoroughly, we can bridge the gap between technical cloud usage and financial accountability—ensuring transparency, optimization, and better cloud cost governance.

On October 20, 2025, a significant AWS outage shook the digital world, causing widespread disruption across numerous popular apps, websites, and services. This incident serves as a crucial case study for cloud infrastructure resiliency and the risks of heavy cloud dependency.

What Happened?

The outage originated from a problematic update to DynamoDB’s API, a core AWS managed database service. This update triggered failures in the Domain Name System (DNS) — the system responsible for translating web addresses into server IPs. When DNS became unavailable, many AWS services couldn’t locate critical infrastructure, resulting in cascading failures impacting 113 AWS services for hours before AWS fully restored operations.

Many Companies were Impacted

Major global platforms faced outages or degraded service during the event, including:

Snapchat
Pinterest
Fortnite
Roblox
Venmo
Reddit
Lloyds Bank
Disney+
Canva
Amazon’s own retail and support systems

Lessons that I/We can Learn

1. Cloud Dependency Risks

The outage exposed the vulnerability of placing critical workloads in a single cloud region or provider. Many businesses suffered simultaneous downtime due to this concentrated dependency.

2. Complex Interdependencies Matter

A seemingly isolated change in one service (DynamoDB) caused widespread failure due to interlinked dependencies, particularly DNS. This reveals the need for robust end-to-end testing for critical infrastructure changes.

3. Resiliency Requires Multi-Region Strategies

To reduce the impact of regional cloud failures, companies must design multi-region or even multi-cloud architectures allowing failover to unaffected zones.

4. Importance of Transparent Communication

Amazon’s responsive communication and public updates helped manage the impact on customer trust and expectations during the outage.

We can Prevent Future Outages

To guard against similar incidents, organizations and cloud providers should:

Design multi-region, redundant architectures to avoid single points of failure.
Implement thorough testing for updates on core infrastructure and APIs.
Develop applications that can gracefully degrade or fallback when dependent services fail.
Maintain robust disaster recovery and incident response plans, including regular simulation drills.

Cloud Route Limits: Why AWS and Azure BGP Restrictions Matter (and How to Overcome Them)

usXCloudSec — Thu, 30 Oct 2025 10:26:32 +0000

When you’re about to launch a groundbreaking hybrid or multicloud project, one of the last things you want to discover is that your carefully architected network design can’t even connect because of BGP route limits.

Unfortunately, that’s the reality for many teams working with AWS Direct Connect or Azure ExpressRoute.

We’ll break down what these limits actually are, why they matter, and how platforms like Aviatrix help enterprises navigate these constraints.

🧭 1. AWS Direct Connect — The 100-Route Limit

According to AWS’s official documentation, for a private or transit virtual interface from on-premises to AWS:

“If you advertise more than 100 routes each for IPv4 and IPv6 over the BGP session, the BGP session will go into an idle state with the BGP session DOWN.”

— AWS Direct Connect Quotas

For a public virtual interface, AWS allows up to 1,000 prefixes, which cannot be increased.

Additional confirmation from AWS’s networking blog notes:

“There is currently a limit of 100 advertised prefixes over the transit VIF. If the prefix count exceeds 100, the BGP session will go into an idle state.”

— AWS Networking Blog

✅ Fact: AWS supports a maximum of 100 BGP routes (IPv4 and IPv6) on private or transit VIFs. Exceeding this limit brings the BGP session down.

💡 What this means for architects:

If your on-premises data center needs to advertise more than 100 distinct prefixes into AWS, you’ll hit a hard limit — causing the BGP session to drop into an idle state.

You’ll need to summarize, aggregate, or re-architect your routing strategy.

☁️ 2. Microsoft Azure ExpressRoute — Prefix Advertisement Limits

From Microsoft Learn:

“There’s a maximum of 1,000 IPv4 prefixes advertised on a single ExpressRoute connection from a Virtual Network to on-premises.”

— ExpressRoute FAQ

For private peering, Microsoft states:

“ExpressRoute supports up to 4,000 IPv4 prefixes and 100 IPv6 prefixes advertised to Microsoft through the Azure private peering. This limit can be increased up to 10,000 IPv4 prefixes if the ExpressRoute Premium add-on is enabled.”

— ExpressRoute Routing Requirements

👉 Tip: The 1,000-prefix limit refers to the number of routes the Virtual Network Gateway can advertise to ExpressRoute — i.e., from Azure to your data center.

✅ Fact:

1,000 IPv4 prefixes from Azure vNet to on-prem (Standard)
4,000 IPv4 prefixes to Microsoft (Private Peering)
10,000 IPv4 prefixes with ExpressRoute Premium

💡 What this means for architects:

If your Azure environment spans multiple VNets, each with many subnets, you could easily exceed these limits. Like AWS, the fix requires route summarization or custom overlay solutions.

⚙️ 3. Why These Limits Matter

These hard limits are not theoretical — they can break production BGP sessions if exceeded.

For example:

An enterprise with hundreds of branch offices, each advertising its own subnet, could instantly exceed AWS’s 100-route cap.
A global deployment spanning multiple Azure VNets could breach the 1,000-prefix ceiling, stopping route propagation to on-prem.

When BGP sessions go idle, connectivity between your data center and cloud environments fails. For large-scale cloud migrations or mission-critical workloads, that can mean downtime, outages, or failed go-live events.

🛡️ 4. How Aviatrix Helps

While cloud providers define the boundaries, Aviatrix extends what you can do within them.

Aviatrix provides:

Intelligent route summarization and route orchestration
Overlay networking that abstracts away CSP limitations
Multicloud visibility and control across AWS, Azure, and GCP
Security and segmentation built into the network fabric

By using Aviatrix, enterprises can navigate CSP limits without breaking compliance or connectivity — allowing consistent architectures across clouds.

📘 5. Summary Table — Cloud Route Limits at a Glance

Cloud Provider	Service	Route Limit (Default)	Notes
AWS	Direct Connect (Private/Transit VIF)	100 routes (IPv4 + IPv6)	Exceeding causes BGP Idle/Down
AWS	Direct Connect (Public VIF)	1,000 prefixes	Cannot be increased
Azure	ExpressRoute (vNet → On-Prem)	1,000 IPv4 prefixes	From vNet Gateway
Azure	ExpressRoute (Private Peering)	4,000 IPv4 prefixes	Can increase to 10,000 with Premium
Aviatrix	Multicloud Overlay	Extends routing & visibility	Works across AWS, Azure, GCP

🧩 Key Takeaways

Every cloud provider has hidden networking limits.
Exceeding them can cause BGP session failures.
Route summarization, overlays, and orchestration tools like Aviatrix can help you operate effectively in hybrid and multicloud environments.
As a network/security architect, know your limits before you deploy — not after the BGP session drops.

Design Consideration for Cloud Migration with AWS

usXCloudSec — Fri, 10 Oct 2025 14:58:06 +0000

Moving your infrastructure and applications from on-premises data centers to the cloud is one of the most transformative steps an organization can take. This guide dives deep into the motivations behind cloud adoption, the challenges faced during migration, critical design considerations, and practical strategies specifically focusing on AWS — the world’s leading cloud service provider.

Why Move to the Public Cloud? The Business and Technical Drivers

Migrating infrastructure to AWS means transitioning from owning and managing physical servers to leveraging scalable, on-demand cloud resources. This shift is motivated by several powerful factors:

1. Achieving Business Agility, Automation, and Innovation

The cloud fosters a culture of agility where development teams can rapidly build, test, and deploy applications. Through infrastructure as code (IaC), automated pipelines, and managed services, AWS enables organizations to innovate continuously and shorten the time to market for new products and features.

2. Ensuring High Application Availability and Fast Turnaround

AWS regions span the globe with multiple availability zones designed for fault tolerance. Applications deployed on AWS benefit from resilient infrastructure that supports rapid updates and meets stringent uptime requirements, essential for meeting customer expectations in competitive markets.

3. Leveraging Auto-Scaling for Elastic Resource Management

AWS Auto Scaling dynamically adjusts compute, storage, and networking capacity according to workload demand. This self-regulating mechanism ensures optimal application performance during peak usage while reducing costs during low utilization periods.

4. Transitioning from CapEx to OpEx with Pay-as-You-Go Pricing

Traditional data centers require heavy upfront capital expenditures on hardware. AWS’s consumption-based pricing model charges only for used resources, enabling financial flexibility. This allows organizations to better align IT spend with actual business activity and scale seamlessly as demand grows.

Understanding Cloud Networking and Security Challenges in AWS

Migrating to AWS requires rethinking networking and security — no longer can organizations rely solely on legacy on-premises paradigms.

Reduced Direct Control and Traditional Visibility: In AWS, networking components such as VPCs, subnets, route tables, and Security Groups replace physical routers and firewalls, requiring new management approaches.
Non-Standardized Networking Constructs: Each AWS service introduces unique networking features and integration points. Designing networks demands a deep understanding of these components and their interactions.
Distributed Security Requirements: The cloud operates on a shared responsibility model. Customers must architect security with distributed enforcement mechanisms aligned with AWS services like AWS WAF, Shield, and IAM, rather than relying on traditional perimeter defenses.
Operational Complexity: Native AWS tools provide some monitoring and troubleshooting capabilities (e.g., VPC Flow Logs), but advanced operational visibility and rapid fault isolation often demand third-party solutions or custom deployments.

Core AWS Networking Design Considerations

When designing your AWS network to support cloud-native applications, four primary factors stand out:

1. Simplifying Complex AWS Network Architectures

AWS offers essential building blocks such as VPCs, Internet Gateways, NAT Gateways, Security Groups, and Route Tables. However, creating a functional architecture that aligns with business use cases is complex and often involves assembling multiple services. It’s crucial to adopt modular, reusable templates based on best practices to reduce configuration errors and increase maintainability.

2. Enhancing Network Visibility for Security and Troubleshooting

Although AWS provides basic logging (e.g., VPC Flow Logs), these logs are raw and often costly to store and analyze at scale. Effective security monitoring and rapid issue resolution require tools that aggregate, visualize, and correlate network telemetry across your AWS environment.

3. Implementing Robust, Distributed Security Controls

AWS enables security policy enforcement at multiple layers: network, instance, application, and identity. Employing multi-layered controls such as Security Groups, Network ACLs, AWS WAF, and Shield, combined with centralized policy management, ensures comprehensive protection without degrading performance.

4. Controlling and Forecasting AWS Networking Costs

AWS networking costs can accumulate rapidly due to charges like data transfer, NAT Gateway usage, and Elastic Load Balancer hours. Establishing budgets, monitoring cost drivers, and optimizing architectures (e.g., using PrivateLink or VPC endpoints) help maintain financial predictability.

Common Pitfalls and How to Avoid Them

Avoid ‘Lift and Shift’ of On-Premises Networking: Simply replicating traditional data center designs in AWS often results in suboptimal performance and higher costs. Instead, embrace cloud-native networking designs.
Beware Over-Reliance on Native Blackbox Automation: AWS provides powerful primitives but lacks integrated visibility and management. Manual stitching of services can lead to brittle architectures difficult to troubleshoot.
Do Not Ignore Cloud-Native Security Models: Centralized perimeter security is insufficient; distributed security policies integrated with AWS services are essential.
Avoid Cost Blindness: Without proper monitoring, networking expenses can spiral. Proactive cost governance and architecture reviews are critical.

Leveraging Aviatrix to Optimize AWS Networking and Security

To address these challenges, many organizations adopt third-party solutions like Aviatrix for cloud network and security management:

Unified Multi-Cloud Management: Manage AWS, Azure, Google Cloud, and others from a single pane of glass.
Advanced Network Visibility with CoPilot: Gain deep insights into traffic flows, patterns, and security posture.
Centralized Security Policy Control: Apply consistent network security policies with distributed enforcement, meeting compliance needs.
Predictable Pricing: Aviatrix offers fixed, transparent pricing models that simplify FinOps planning and control.

Final Thoughts: Succeeding in Your AWS Cloud Migration

Migrating to AWS is a strategic journey that demands thoughtful network and security design. Key takeaways include:

Harness AWS agility and automation to accelerate innovation.
Design networks that are simple, secure, visible, and cost-efficient.
Avoid legacy on-premises approaches and embrace cloud-native architectures.
Use complementary tools such as Aviatrix to extend AWS capabilities and simplify operations.

By thoughtfully approaching AWS cloud migration with a focus on these principles, organizations can unlock powerful benefits and drive business transformation.

AWS IAM: Permissions and Policies ?

usXCloudSec — Wed, 30 Jul 2025 02:38:16 +0000

AWS Identity and Access Management (IAM) is a critical service that controls secure access to AWS resources. At its core, IAM governs who can do what to which resources in your cloud environment, ensuring security and operational smoothness. This blog will explore the foundational concepts of permissions and policies in AWS IAM, how they interact, and how you can leverage them effectively with practical examples.

What is AWS IAM?

AWS IAM lets you safely manage access to AWS services and resources. By using IAM, you define identities (like users, groups, and roles) and assign them permissions through policies that specify what actions they can perform on which AWS resources.

Key Concepts: Permissions vs Policies

Permissions are the allowed or denied actions a user or system can take on AWS resources.
Policies are the documents written in JSON format that define these permissions. Effectively: Policies describe permissions.

Types of IAM Policies

AWS supports several policy types, each with distinct purposes:

Policy Type	Description	Practical Use Case
Identity-based Policies	Attached directly to IAM users, groups, or roles. Grants permissions to the identity.	Granting a developer access to start EC2 instances.
Resource-based Policies	Attached to AWS resources (e.g., S3 bucket policies). Grant access to specified principals.	Allowing another AWS account to read your S3 bucket.
Managed Policies	Predefined by AWS or custom policies created by you, reusable across multiple entities.	AWS Managed Policy: `AmazonS3ReadOnlyAccess`.
Inline Policies	Embedded directly into a single user, group, or role. Not reusable.	Unique permissions needed for one specific user.
Permissions Boundaries	Define the maximum permissions an identity can have, acting as a limit rather than a grant.	Restricting junior admins from escalating privileges.
Service Control Policies (SCPs)	Used within AWS Organizations to limit permissions across all member accounts.	Forcing organization-wide restrictions on IAM changes.
Session Policies	Temporary policies passed during role assumption to limit permissions dynamically.	Restricting permissions in a federated user session.

Anatomy of an IAM Policy Document

An IAM policy is a JSON file, which includes one or more statements—each defining:

Effect: Allow or Deny — whether the action is permitted or forbidden.
Action: AWS service actions (e.g., s3:GetObject).
Resource: Specifies which exact resource(s)—defined by Amazon Resource Names (ARNs)—the policy applies to.
Condition: Optional extra controls (e.g., IP restrictions, time constraints, MFA requirements).

Example: Restricting S3 Access by IP

Here’s a sample policy allowing all S3 actions on a bucket company-data but only from your corporate IP address:

{ "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Action": "s3:", "Resource": "arn:aws:s3:::company-data/", "Condition": { "IpAddress": { "aws:SourceIp": "203.0.113.10/32" } } }] }

This policy creates a strong security boundary by allowing access only from trusted network locations.

The Principle of Least Privilege

A core security practice in IAM is granting only the minimal necessary permissions for users and applications to perform their tasks. This principle reduces exposure and limits damage if credentials are compromised.

How Permissions Are Evaluated

When a principal (an authenticated user, group member, or role) attempts an AWS action:

AWS evaluates all relevant policies attached to the principal and to the resources involved.
Explicit Deny permissions in any policy take precedence and block access.
If no policy explicitly allows the action, it is implicitly denied.
If any policy grants permission and no explicit deny blocks it, the action is permitted.

For instance:

A developer with a policy allowing ec2:StartInstances but no mention of ec2:TerminateInstances cannot terminate instances.
If the same developer has another policy explicitly denying ec2:TerminateInstances, the deny overrides any allow.

IAM Roles and Temporary Permissions

IAM roles provide a secure method to delegate permissions without sharing long-term credentials. They are assumed by trusted entities (like EC2 instances, Lambda functions, or users from external accounts). When a role is assumed, temporary security credentials with the role’s permissions are issued.

Roles have two key policy types:

Trust policy: Defines who can assume the role.
Permissions policy: Defines what the role can do.

Real-World Policy Examples

1. Read-Only Access to S3 Buckets

{ "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Action": ["s3:ListBucket", "s3:GetObject"], "Resource": ["arn:aws:s3:::*"] }] }

This lets users list and read any S3 bucket objects without write permission.

2. Restrict Deletion Without MFA

{ "Version": "2012-10-17", "Statement": [{ "Effect": "Deny", "Action": "s3:DeleteObject", "Resource": "arn:aws:s3:::sensitive-data/*", "Condition": { "BoolIfExists": { "aws:MultiFactorAuthPresent": "false" } } }] }

This denies object deletion unless multi-factor authentication is enabled — adding a valuable security layer.

Advanced Controls: Permission Boundaries & SCPs

Permission Boundaries limit the maximum permissions assignable to an IAM entity, an important safeguard in complex environments.
Service Control Policies (SCPs) enforce account-wide or org-wide permission limits, helping comply with organizational governance and security compliance.

Best Practices for IAM Permissions and Policies

Start with AWS Managed Policies to cover common roles but customize to tailor security.
Use IAM Groups to simplify management by assigning policies collectively.
Regularly review and update policies to remove unused privileges.
Use conditions (like source IP, MFA, or VPC restrictions) to tighten security.
Monitor permissions usage with AWS Access Advisor and IAM Access Analyzer tools.
Audit policies for overly broad permissions (*) and minimize their use.

Wrapping Up

AWS IAM policies and permissions form a sophisticated and flexible system essential for securing your cloud environment. By understanding the different policy types, the structure of policies, how permissions are evaluated, and following best practices, you can design robust access controls that protect your resources without hindering productivity.

Beyond the Server Room: Transform Your IT Career with AWS

usXCloudSec — Sun, 20 Jul 2025 02:30:35 +0000

Three data center technicians—Omar Ahmed, Paige Broderick, and Omar Mahmoud—once knew every inch of the server room: the hum of machines, the rhythm of routine maintenance, and the challenges of physical infrastructure.

Today, they’ve transitioned into AWS Solutions Architects, designing resilient and scalable enterprise solutions powered by the cloud. This is their journey—and it could be yours too.

In this blog, you'll discover the three-phase approach they followed and learn how to map out your own cloud career path using AWS Skill Builder and other free resources.

Meet the Architects

👨‍💻 Omar Ahmed

Began as a Data Center Operations Technician, troubleshooting hardware and network systems. His hands-on experience formed the foundation for understanding advanced AWS services.

👩‍💻 Paige Broderick

Now a Solutions Architect at AWS, she started in Data Center Engineering, maintaining backup power systems. Her background helps her guide enterprise clients in the semiconductor and software industries.

👨‍💻 Omar Mahmoud

With roots in data center operations, Omar now helps businesses architect resilient, cost-effective cloud solutions tailored to their needs.

Their stories share one lesson: you can start small and scale your skills just like cloud infrastructure.

🧭 Phase 1: Getting Started with Cloud Computing

If you’ve worked in traditional IT or infrastructure, you already hold valuable knowledge. Physical components like:

Servers → EC2 Instances
Network cables → VPCs and Subnets
Power backup and redundancy → High availability and fault tolerance

This kind of hands-on knowledge translates directly to cloud concepts.

🚀 Start Learning with AWS Skill Builder

AWS Skill Builder provides:

Over 600 free courses
Learning plans
Official practice questions
Beginner-friendly courses like:
- AWS Technical Essentials
- Security Fundamentals
- Machine Learning & AI Fundamentals

📌 Tip: Take your time—spend 3 to 6 months solidifying your cloud foundation. It’s better to build slow and strong than rush and forget.

📚 Phase 2: Deepen Your Cloud Knowledge

Once you're comfortable with core concepts, it’s time to get certified.

🏅 Start with AWS Certified Cloud Practitioner

Validates your understanding of:
- AWS services
- Cloud terminology
- Core use cases
Supported by AWS Cloud Quest: Cloud Practitioner, a gamified training platform that awards points for lab completion.

🏗 Move to Solutions Architect – Associate

This certification requires deeper architectural thinking and knowledge of service integrations.

Recommended prep resources:

AWS Exam Prep: Solutions Architect – Associate (SAA-C03)
Official practice exams
AWS Skill Builder Individual subscription (for labs and sandbox practice)

🛠 Phase 3: Hands-On Experience and Specialization

Once you know the basics, start building real-world projects and explore certifications in your area of interest:

DevOps
Security
Networking
Machine Learning

⚡ Where to Practice

AWS Immersion Days: Free virtual events with labs led by AWS Experts.
AWS Workshops: 100+ self-paced tutorials that simulate real-world use cases.
Getting Started Resource Center: Over 90 tutorials, videos, and guides.

🌱 Begin Your Cloud Journey Today

The cloud world can feel overwhelming at first. Here’s a simple 4-step action plan to help you begin:

Take a fundamental course like AWS Technical Essentials.
Identify your knowledge gaps and fill them gradually.
Block time for daily or weekly study.
Set a goal—like earning the AWS Certified Cloud Practitioner.

🌟 Every AWS expert started right where you are today.

Persistence, hands-on learning, and a structured path can take you from racking servers to architecting scalable solutions for global enterprises.

🌍 Driving Sustainable Innovation at AWS: Hilary Tam’s Journey

usXCloudSec — Sat, 19 Jul 2025 09:09:39 +0000

Sustainability is no longer a side initiative—it’s becoming the heart of how forward-thinking companies operate. At Amazon Web Services (AWS), one leader is helping shape a future that serves people, profits, and the planet.

Meet Hilary Tam, AWS's Commercial Sustainability Leader for Europe, Middle East, and Africa (EMEA), who is turning bold climate ambition into practical, scalable solutions.

🌱 From a Tea Farm to Global Change

Hilary’s passion for sustainability began early, but a visit to a multi-generational green tea farm in China left a lasting impression. She witnessed firsthand how unpredictable climate patterns were impacting crop quality and livelihoods. That experience sparked a mission: to use human-centered innovation to tackle complex environmental issues.

💼 What Does a Commercial Sustainability Leader Do?

At AWS, Hilary collaborates with customers and partners to drive sustainable innovation. Her mission?

“Good for people and planet is also good for business.”

She helps businesses align their unique capabilities with the United Nations’ Sustainable Development Goals (SDGs), transforming climate risk into a competitive advantage.

📊 Understanding the Big Picture: Scope 3 Emissions

One of the biggest sustainability hurdles companies face is Scope 3 emissions—those outside their direct operations.

🔍 Did you know? Between 80% to 95% of an organization’s carbon footprint often lies in Scope 3—suppliers, partners, and customers.

Hilary believes technology and data are key to tackling this challenge. Manual tracking is outdated—today’s sustainability leaders must leverage cloud infrastructure to gain visibility and take action.

🚀 Innovating Toward Net Zero

According to Tam:

“40% to 60% of the innovations needed to reach net zero by 2050 haven’t been fully developed or deployed at scale.”

That’s where cloud services like AWS come in—accelerating digital transformation to support climate goals.

🔄 Nature and Climate Are Interconnected

Hilary stresses that sustainability isn't just about carbon emissions. Restoring biodiversity and protecting nature are equally critical. Through partnerships like the one with the Natural History Museum, AWS supports data-driven insights that can guide conservation efforts across industries.

🛠️ Tips for Aspiring Sustainability Leaders

If you think sustainability is someone else’s job—think again.

“Those without 'sustainability' in their job titles will increasingly be responsible for executing sustainability strategies,” says Tam.

Her advice? Start small. Think big. Go fast.

Hack sustainability into your existing work
Build on your existing expertise
Use storytelling to inspire action—but back it with data and results

🧠 Final Thoughts

Hilary Tam is helping shift the sustainability narrative—from limiting harm to creating net-positive impact. Her work embodies AWS's principle:

“Success and Scale Bring Broad Responsibility.”

Whether you're a developer, designer, engineer, or business leader—there’s a role for you in shaping a sustainable digital future.
