SRE vs. DevOps: Which is the Better Software Delivery Methodology?

The IT sector has flourished beyond bounds in the previous decade, making software pivotal for modern businesses. With their increasing reliance on software, the market has released numerous methods to cope with their needs. Two of such methods are DevOps and SRE – the pinnacle of software development and deployment.

The approaches have become the market meta, with most industry leaders equipping at least one of them. While this provides clarity, it also breeds confusion for many ventures. Not every business can afford to integrate both SRE and DevOps to find a better alternative.

Thus, arises the ultimate dilemma – what is the better alternative between SRE Vs DevOps. Declaring one of them the better option will not be viable as they contain different processes and identities. So how can you find which to choose between the two?

You can start by understanding their fundamentals and differences by attaining DevOps training. On that note, here are everything businesses should know about site reliability engineer vs DevOps.

DevOps or SRE: A Brief

Before delving into the complexities of SRE and DevOps, it is crucial to comprehend their basics. Let us dig deeper into the fundamentals of the approaches:

DevOps

Development and Operations, known as DevOps, is a culture and concept designed to facilitate a quick, stable, and secure software release. It stands as the intersection of ESM (Enterprise Systems Management) and Agile development practices.

In the traditional software development procedures, programmers or developers were accountable for coding and crafting the necessary features. Similarly, operations took the initiative to deploy the features and maintain their functionality.

As expected, dividing the tasks into silos rendered constant conflicts between the departments. It initiated the original need for a solution that allows Devs and Ops to operate together, hence DevOps.

DevOps is a structural mindset, principles, and a concept designed to reduce friction and gaps between the operations and developments department. It comprises practices and concepts related to software building and delivery. The core difference between SRE and DevOps is implementation since there are no specific guidelines to implement DevOps.

It solely operates by virtue of seamless communication and collaboration between production and development teams.

SRE (Site Reliability Engineering)

SRE proposes a unique approach to software lifecycle and management by integrating different development prospects into IT operations. The term first emerged at Google in 2003 to develop an IT framework that addresses the demands of enterprise-scale mechanisms.

The method allowed businesses to divide the infrastructure into basic and abstract components, establishing the primary difference between DevOps and SRE. Site Reliability Engineering allows businesses to implement automation to resolve software production-related issues. In a way, SRE is the method that supports DevOps practices and philosophies, helping enterprises execute them optimally.

SRE vs. DevOps: The Difference

The core aim of both methods is to minimize gaps between operations and development teams. However, the concepts differentiate on multiple facets, and here is an overview of them:

Essence

DevOps emerged as an accumulation of philosophies that enables the mindset of collaboration and culture between siloes teams.

Contrarily, enterprises came up with SRE to narrow their focus, creating a set of metrics and practices that facilitates improved service deployment and collaboration.

Aim

As mentioned already, both approaches aim to render seamless proceedings between operations and development personnel. However, DevOps acts as the template that maps collaboration while SRE comprises prescriptions of achieving reliability.

Structure

The team structure is yet another crucial difference between DevOps and SRE. A DevOps team includes several roles, such as developers, SREs, QA experts, engineers, and several more. Contrarily, an SRE team comprises site reliability engineers with a rich background in development and operations.

Focus

DevOps emphasizes the development and deployment speed of the software while maintaining continuity. On the other hand, site reliability engineering focuses on elevating system reliability and availability.

SRE vs. DevOps: Use-Cases and Applicability

Besides the basic difference between the concepts, businesses should also understand their applicability for a better orientation.

Why Enterprises Adopt DevOps?

Achieving engineering efficiency requires multiple tools since it has a wide spectrum. Even nowadays, most businesses look for one skilled DevOps engineer despite the apparent workload it puts on the individual.

The software delivery life cycle is a treacherous road, and DevOps tries to smoothen it. The DevOps team achieves it by eliminating barriers to automation and production. Agile’s mainstream popularity leads to innovative production changes, requiring businesses to deploy prompt updates.

That is why the DevOps team uses multiple development tools, undertaking processes from the initial guidance, source code monitoring to Continuous Integration (CI) and Continuous Delivery (CD.)

Why Enterprises Adopt SREs?

SRE teams primarily focus on health, safety, solution remedying, and uptime. This is what establishes another major difference between a site reliability engineer vs DevOps engineer. To achieve the goal, site reliability engineers hone skills in three distinct departments – SLAs, SLOs, and SLIs.

SLAs or Service Level Agreements refer to the agreement businesses make with customers. They might be external, internal, or any other system-related. Businesses generally establish SLAs around system or customer expectations. Despite being present for several years, SRE popularized the concept of SLAs among modern businesses.

SLOs or Service Level Objectives are objectives that ensure the fulfillment of the SLAs. As SLIs ensure that the business achieves its SLAs, businesses also integrate Google’s Four Golden Signals into the process. Added with saturation, it serves as the ultimate SLAs-facilitating system.

SLIs or Service Level Indicators measure conformance with an SLO. It analyses how the SLOs are performing, making it an integral component for SREs. It establishes another site reliability engineer vs DevOps as DevOps teams do not merely look at SLIs for engineering efficiency; they also assess Accelerate metrics.

In Conclusion

SRE vs. DevOps is a complex debate since both approaches render esteemed results. However, modern businesses must understand the differences and relationships between the two to execute them properly. Enrolling in a DevOps certification can make you understand the differences at ease. Striking a balance between the two can help enterprises unlock their optimal potential. The goal is to first assess the difference between DevOps and SRE and formulate a strategy around it.
