Creating an EC2 Instance

Ogundu Ahamefule — Sat, 03 Jan 2026 13:45:36 +0000

An EC2 instance is Amazon Web Services’ (AWS) version of a virtual machine (VM). It’s a resizable compute resource in the cloud that behaves like a traditional VM but is hosted and managed on AWS infrastructure.

🖥️ EC2 Instance vs. Virtual Machine

Feature	EC2 Instance (AWS)	Traditional Virtual Machine
Definition	A cloud-based compute resource provided by AWS.	A software-based emulation of a physical computer running on local hardware or private cloud.
Hosting	Runs on AWS’s global infrastructure (data centers).	Runs on your own hardware or a hypervisor (like VMware, VirtualBox).
Scalability	Instantly scalable up or down; pay-as-you-go.	Limited by local hardware capacity; scaling requires manual upgrades.
Management	AWS manages hardware, networking, and availability zones.	You manage the physical server and hypervisor.
Use Cases	Web hosting, app servers, machine learning, analytics, enterprise workloads.	Development environments, desktop virtualization, on-premises servers.

FUNDERMENTAL CONCEPTS OF CLOUD COMPUTING

Ogundu Ahamefule — Sun, 02 Nov 2025 13:58:58 +0000

What is cloud computing? Cloud computing refers to the on-demand delivery of computing services such as servers, storage, databases, networking, software, and analytics over the internet. It eliminates the need for businesses and individuals to own and manage physical infrastructure, offering a scalable, flexible, and cost-effective alternative. Users only pay for the resources they consume, enabling efficient resource utilization and cost savings.

Cloud computing operates through a network, typically the internet, where users access shared resources hosted on remote servers managed by cloud providers. A central server facilitates communication between client devices and these servers, ensuring secure and seamless data exchange.

Define virtualization? Virtualization in cloud computing is the process of creating virtual versions of physical resources—like servers, storage, and networks—to maximize efficiency, scalability, and flexibility.

Define scalability? Scalability in cloud computing refers to the ability of a system to handle increasing or decreasing workloads by adjusting its resources—like computing power, storage, or bandwidth—efficiently and seamlessly.

Define Agility? Agility in cloud computing refers to the ability of an organization to rapidly adapt to changing business needs by leveraging flexible, scalable, and on-demand cloud resources. It’s about speed, responsiveness, and innovation.

Define high availability? High availability in cloud computing refers to a system’s ability to remain operational and accessible nearly 100% of the time, even during failures or maintenance. It ensures that services are consistently up and running without interruption.

Define fault tolerant? Fault tolerant in cloud computing is the ability of a system to continue operating properly even when one or more components fail. It ensures uninterrupted service delivery despite hardware, software, or network issues.

Define Global Reach? Global reach in cloud computing refers to the ability of cloud services to operate and deliver resources across multiple geographic regions worldwide, ensuring low-latency access, high availability, and seamless scalability for users regardless of location.

What is the difference between elasticity and scalability?
Scalability is about long-term growth capacity, while elasticity is about short-term adaptability to fluctuating demand.
