SRE vs DevOps: Which Productivity Approach is Better?

When a new concept emerges in software development, companies increasingly adopt methodologies that allow for dependable and scalable software. Two concepts have been trending in IT for the past few years: DevOps and Site Reliability Engineering (SRE). They both coexist in the fields of software development and deployment.

Both these may appear to be competitors at first glance. However, deep insights revealed that alleged competitors have distinct processes and identities to meet the requisite goals. While different in their approaches, Site Reliability Engineering vs DevOps share a common goal of bridging the gap between development and operations teams to improve the software life cycle without compromising quality. SRE teams focus on maintaining the reliability and stability of systems, while DevOps teams emphasize the collaboration and integration of development and operations. For the past few years, the rise of these approaches and practices has become mainstream.

According to Dynatrace, a leading software intelligence platform, 88 percent of SRE respondents believe they have a deeper understanding of the strategic importance of their role now than they did three years ago. However, 99 percent of these respondents also reported facing challenges when creating and designing SLOs to evaluate service levels for infrastructure and applications. Despite these challenges, the benefits of SRE are undeniable. Improved system reliability and reduced downtime are among the key advantages. Looking ahead, 85 percent of SRE respondents anticipate the need to run the same observability platform from development to operations and security by 2025. This could pose a challenge, but it also promises consistency and efficiency.

Another survey conducted by Transposit firm on National DevOps Day stated that two-thirds of respondents (63 percent) had noticed a rapid growth in service incidents after affecting their clients during the last 14 months. Furthermore, in the DevOps workflow, over half of respondents (58 percent) said that downtime for their company could be up to USD 4,99,999 per hour on average, with 40% informed that the cost increased in the previous year. DevOps consulting services can be crucial here, helping organizations mitigate downtime costs and optimize their DevOps strategies to prevent such service incidents.

Before delving deep into the significant difference between Site Reliability Engineering (SRE) and DevOps, let’s explore the concepts first.

What is Site Reliability Engineering (SRE)?

The concept of Site Reliability Engineering (SRE) originated at Google in 2003 under the direction of Ben Treynor Sloss, vice president overseeing technical operations at Google. In recent times, SRE has gained much traction in the IT world.

Google’s vice president Treynor Sloss said, “So SRE is fundamentally doing work that an operations team has historically done, but using engineers with software expertise, and banking on the fact that these engineers are inherently both predisposed to, and can, substitute automation for human labor.”

SRE combines system operations responsibilities such as latency, performance, ensuring availability, scalability, capacity, and software system deployment. SRE tools offer a unique model for service management and application life cycle by integrating various aspects of software development into IT operations.

SRE measures a system’s performance using three Service Level Commitments.

1) Service Level Agreements (SLAs)

SLA is a documented agreement between a client and a service provider, mainly what services a service provider will offer and the standard.

2) Service level objectives (SLOs)

Service level objectives (SLOs) cater to values and goals created by SRE teams that must be met to meet SLAs.

3) Service Level Indicators (SLIs)

SLIs are metrics and attributes that show how well a system complies with SLOs. Typical SLIs include development frequency, mean time to restore (MTTR), system throughput, request latency, lead time, and availability error rate.

Benefits of SRE

Whereas DevOps improves company collaboration and speed, one of the primary benefits of SRE is increased uptime. Their focus is primarily on service operational or software platforms. SRE aims to keep things operational, and tasks such as prevention, reliability, redundancy, and disaster management are paramount.

The goal of the SRE team is to figure out the best solutions to avoid issues that could result in downtime and keep things running. This is especially key for managing large-scale systems. Site reliability engineering allows businesses to minimize manual tasks, giving developers more time to create innovative ways. Moreover, in SRE DevOps, any flaws are swiftly identified and rectified efficiently.

Roles and responsibilities of SRE

The purpose of SRE in an organization is quite simple: The SRE team ensures that the service or platform is available to clients whenever they require it. In addition, through the refinement and automation of routine processes, an SRE DevOps ensures seamless collaboration between development teams and IT operations.

Some responsibilities of an SRE include:

• Software development, configuration, and deployment for operations teams
• Taking care of escalation flaws in support
• Reviewing incidents and reporting on them
• Creating documentation for the system
• Management changes
• Approving and determining new features and enhancements and developing system documentation.
• SRE enables developers to develop more dependable systems by focusing on development and operations. As a result, the developers have a far better perspective for supporting production systems.

What is DevOps?

Andrew Clay and Patrick Debois coined the concept of DevOps in 2008. The movement began to coalesce between 2007 and 2008 when software development and IT operations teams raised issues about what they witnessed as a terminal degree of dysfunction in the industry.

DevOps combines tools, practices, and cultural philosophy that improve work through implementing lean practices and agile in a system-oriented model. Simply, it is an approach to software development. Developers or programmers were responsible for developing and coding the required functionality in the traditional software development lifecycle. It combines practices and concepts related to software delivery and development with DevOps services, allowing organizations to streamline workflows and enhance collaboration. DevOps also permits improved customer satisfaction and reliable service delivery by collaborating and communicating between cross-functional teams.

DevOps Methods and Practices

Continuous, incremental improvements are the foundation of DevOps processes, aided by automation. While full automation is rarely attainable, a DevOps methodology focuses on the following factors for total automation:

Continuous Integration and Continuous Delivery (CI/CD)

DevOps aims to update and deliver apps to clients as quickly as possible. DevOps automates releasing and updating code into production using CI/CD pipelines to connect procedures and processes.

Continuous monitoring and deployment are also part of CI/CD to maintain code consistency across multiple software versions and deployment environments.

1) Infrastructure as code

DevOps emphasizes the abstraction of IT infrastructure so that it may be provisioned and controlled automatically using software engineering methodologies. Consequently, you’ll have an efficient system that permits your team to monitor infrastructure configurations and track changes that have unanticipated or undesirable consequences that should roll back.

2) Automated Testing

While updating or writing the code, it is continuously and automatically tested. The continuous mechanism accelerates deployment by eliminating bottlenecks associated with pre-release testing.
