Multi Cloud Observability with Open Telemetry

Simplify Multi-Cloud Observability with Open Source

Overview

As cloud workloads become increasingly sophisticated, adopting an open-source and vendor-agnostic approach is key to streamlining organizational operations. This article explores how organizations can leverage open-source solutions to simplify observability across multiple cloud environments.

The Challenge with Traditional Observability

Before open-source solutions like OpenTelemetry, observability was fragmented and vendor-specific. Organizations would:

  • Import vendor-specific SDKs as dependencies (e.g., Azure Monitor SDK)
  • Couple their applications tightly to specific cloud providers
  • Face challenges when migrating between cloud platforms
  • Deal with inconsistent telemetry data formats across different tools

OpenTelemetry to the rescue

OpenTelemetry, also known as OTel, is a vendor-neutral open source Observability framework for instrumenting, generating, collecting, and exporting telemetry data such as traces, metrics, and logs.

Key Benefits

  • Vendor-Agnostic: Open source, as well as vendor- and tool-agnostic, meaning that it can be used with a broad variety of observability backends, including open source tools like Jaeger and Prometheus, as well as commercial offerings.

  • Industry Standard: As an industry-standard, OpenTelemetry is supported by more than 40 observability vendors, integrated by many libraries, services, and apps, and adopted by numerous end users.

  • Unified Data Collection: OTel offers a vendor-agnostic, open-source standard for data collection in a market of bespoke commercial tools and narrow open-source monitoring solutions.

Core Components

  1. OpenTelemetry SDKs: Language-specific implementations that bridge APIs and exporters
  2. OpenTelemetry Collector: A vendor-agnostic implementation for receiving, processing, and exporting telemetry data.
  3. APIs and Exporters: Standardized interfaces for data collection and transmission

Benefits for Multi-Cloud Environments

Simplified Operations

  • Reduced Development Time: Companies can spend less time developing a mechanism for collecting critical application data and can spend more time delivering new features instead.

Enhanced Troubleshooting

  • OpenTelemetry simplifies alerting, troubleshooting, and debugging applications.

Future-Proofing

  • Organizations can switch between observability backends without changing application code
  • Consistent telemetry data format across different cloud providers
  • Protection against vendor lock-in

Implementation Approach

The modern approach with OpenTelemetry involves:

  1. Standardized Instrumentation: Use OpenTelemetry SDKs instead of vendor-specific tools
  2. Unified Data Collection: Implement the OpenTelemetry Collector for centralized processing
  3. Flexible Backend Selection: Choose from various open-source or commercial observability platforms
  4. Consistent Monitoring: Maintain the same observability standards across all cloud environments

Conclusion

Open-source observability solutions, particularly OpenTelemetry, provide organizations with the flexibility and standardization needed for effective multi-cloud operations. By adopting vendor-agnostic approaches, teams can focus on delivering value rather than managing complex, proprietary observability toolchains.
