Resilience is the capability to recover quickly from difficulties or toughness. It is not about preventing failures, but being able to recover from them quickly. As Amazon’s CTO Werner Vogels famously said ‘everything fails all the time’. It’s a fact of life that failures will inevitably happen but what we can do is build applications that can withstand different kinds of failures. For example, in a data center, hardware is going to fail all the time.

What happens when the tools and services you depend on to drive Site Reliability Engineering turn out to be susceptible to reliability failures of their own? That’s the question that teams at about 400 businesses have presumably had to ask themselves this month in the wake of a major outage in Atlassian Cloud.

Curious about continuous deployment vs delivery? We explain what each is, what happens in each step, and their importance in the DevOps lifecycle.

We live in the cloud era, where your services don’t live in machines in your garage, but are spread across huge data centers around the world. Cloud providers can help meet increasing demands for reliability – for example, they offer dynamic resource allocation that can handle usage spikes. At the same time, going cloud native means not having a physical server onsite that you can fiddle with, introducing its own unique challenges. ‍

Software reliability is the probability of failure-free operations in a computer program for a specified period of time in a specified environment. It is critical for validation in order to determine characteristics in terms of system performance, functional compatibility, maintenance, competency, installation coverage and process documentation continuance. Software reliability helps you to identify and fix bugs, improve performance, and test features.

Looking into DevOps pipelines? We explain what a DevOps pipeline is, how to build one, and the best practices for building one for your team.

At Nobl9’s annual SLOconf—the first conference dedicated to helping SREs quantify the reliability of their applications through service level objectives (SLOs)—Sumo Logic shared our contribution of slogen to the OpenSLO community, as well as our commitment to OpenSLO as an emerging standard for expressing SLOs as Code. slogen is an open source, SLO-as-code CLI tool based on the OpenSLO specification.

Site reliability engineering (SRE) is a set of principles that incorporates aspects of software engineering into IT operations. It takes tasks that would typically have been done manually by operations teams and gives them to engineers to solve using software and automation. This helps to create a bridge between development and operations teams. The concept of SRE was created by Google back in 2003. Since then, it has been adopted by thousands of organizations all over the world.

Clients expect prompt implementation of changes to their software, and this requirement motivates site reliability engineers to incorporate reliability into applications. The healthy practice of observability and monitoring can improve the reliability and security of software systems. Monitoring is the recording and interpreting data from software systems to keep track of their performance.
