SRE vs. DevOps: Weighing the Differences

In this fast-paced world of IT, the usage of automation techniques is on the rise and is expected to rise in the foreseeable future. For an entrepreneur who wants to stay on top of the business world, it is necessary to meet the average consumer demands of speed, convenience, and reliability for a wonderful digital experience. This encouraged brands to adopt, faster, and more efficient software development and maintenance practices of DevOps and Site Reliability Engineering (SRE). These trending disciplines are accelerating the application delivery by bridging the gap between development and operations teams. It’s a bit difficult to differentiate both the methodologies as share similar core principles and objectives.

Let’s analyze: What DevOps and SRE are? How they relate? What are the differences? What can they do for enterprises? And more.

 

Why DevOps?

DevOps is a cross-department integration between Development/ Code creation and Operations departments. Earlier, the Dev teams use to write code and throw it over the wall for the Operations team to install and support. This leads to considerable dysfunction since the developers want the clients to use the latest code whereas the operations team favors as little changes as possible for a steady system. This introduced instability that affects the end-users and the company. DevOps eliminates this contention by embracing open communication and full transparency between the software development (“devs”) and operations (“ops”) teams.

The term DevOps was coined by Andrew Shafer and Patrick Debois back in 2008 though gained popularity recently as follows agile principles enabling continuous delivery with a frequent release rate. According to Marketsandmarkets, the DevOps revenue will grow to USD 10.31 Billion by 2023 at a CAGR of 24.7%. Nowadays about every company, from a startup to an enterprise, is hiring DevOps. A DevOps Engineer is an excellent coder as well as capable to handle all the Ops functions.

 

Why Site Reliability Engineering (SRE)?

It was a little much to ask developers to understand the infrastructure, including how to deploy, configure, and monitor product service. Here, the role of a site reliability engineer chips in. An SRE focuses on the aspects of software engineering and applies that to resolve the issues of the IT operations. The main goal is to create an ultra-scalable and highly reliable production environment.

The idea of SRE was brought to the surface by Google’s Ben Treynor in 2003 while become prevalent in recent years. A Site Reliability Engineer analyzes the unexpected incidents to prevent future hazards and evaluates new possibilities while handling the operations, monitoring, and alerting.

 

Site Reliability Engineer vs DevOps

Both the DevOps and SRE address organizational needs for production operation management but are significantly different. The differences are listed below:

DevOps

SRE

DevOps is a cultural framework that is embraced through a team as it needs the combined skills of a software engineer, system engineer, architect, and an experienced master. SRE is a practice of maintaining a stable production environment. This role is assigned to software professional.
It combines the development and operation processes and the responsibility of a DevOps engineer is to execute the development automation vision from the start of the project. It provides reliability by implementing the best practices in engineering and operations. A site reliability engineer is responsible for monitoring applications/services after deployment.
DevOps focuses mainly on the automation part. SRE covers aspects like system availability, observability, and scale considerations.
A DevOps engineer has detailed knowledge of the complete SDLC lifecycle as well as experience in implementing changes to tooling for supporting the improved processes. A Site Reliability Engineer ensures that the site is always operational.
DevOps is always on the side of code creation and testing It mainly focuses on the type of environment you are in.
It can be rightly said as a philosophy that aligns business goals with information technology. SRE can be seen as the implementation of the philosophy of DevOps.

 

Similarities

Though SRE and DevOps are different yet have the same measures of success. The reason behind it is very simple. Both disciplines reach to a similar set of conclusions by eroding the business barriers to deliver better software faster. Because SRE gives different approaches to build and maintain the top pillars of the DevOps only. Let’s find the connection as follows:

 

DevOps Pillars

Corresponding SRE Practices

Reducing Organizational Silos Sharing ownership among developers by using the same tools and techniques across the company.
Failure Accepting Environment Providing a formula for balancing accidents and failures against new releases including Service Level Indicators (SLIs) and Service Level Objectives (SLOs). SLIs measure the failures per request and SLO represents the success of SLIs over a certain amount of time.
Implementing Gradual Changes Continually updating the product to move faster while reducing the cost of failure.
Use of Tooling & Automation Maximizing the use of automation and tools as long as providing value to developers and operations by removing manual tasks.
Monitoring Success Defining the prescriptive procedures for measuring availability, uptime, outages, toil, etc. considering that operations, is a software problem.

 

Final Thoughts

All in all, DevOps and Site Reliability Engineering are not competing while complementing each other. SRE is efficacious to implement the DevOps paradigm. DevOps helps to deliver applications and improves products at a faster pace whereas SRE comes into play at the post-deployment stage. Experts are predicting that these will be imperative to drive operational efficiency and productivity in business processes by 2020.
