SRE is the one whose main focus is to look after operation problems in the DevOps lifecycle. It has some set of tools through it works.
SRE is also the same as DevOps but the only thing which makes it different is its main focus which is towards operational problems.
It has been originated in Google company. As you might have never experienced any downtime in Google apps, they always work smoothly even when they work over the apps or services provided through other channels. This smoothness happens with the Google team which is SRE.
SRE is the one who looks after this operation works who 24 Hrs monitors the availability and health of the operational services. SRE is very important nowadays. This is why SRE has precious value in the DevOps process.
Monitoring is a very important aspect of any service because it’s the one who tells about the current health and functions availability of Application.
SRE has a group of teams whose only work is to monitor as well as predict the future consequences, so they can work on that to remove that vulnerability.
SRE is a process that works with software engineers and emphasizes automation solutions to ensure continuously delivered applications are working efficiently and reliably. A major focus of SREs is the desire to never see the solved issue again, often using automation as a resolution.
The role of SRE in DevOps is to ensure that the apps and services that have been developed are available to end-users and should function effectively and reliably. Although SRE and DevOps are two distinct disciplines.
What are the benefits of SRE?
⦁ Observability into the health of services:
⦁ Stronger ties between developers and operations
⦁ Modernization of the NOC
⦁ Organization of on-call structures and alerting workflows
⦁ The surfacing of production concerns
⦁ Stewardship across engineering teams
Top 10 Tools For SRE Engineers
Jira – Jira is a tool that helps in managing work. Jira was brought into the picture in 2002. Prior it was designed to track the issue and project management tool but today it has been evolved with more features that can be used in different cases to agile software development. Jira is a central hub for coding, collaboration, and release phases.
It integrates with the CI/CD tools to feature clarity in the software development lifecycle.
Jira help in focusing on shipping faster, better software by integrating with Atlassian and vendor tools. It can also integrate with first and third-party tools including version control tools like bit bucket, Gitlab, etc, as well as management tools like Confluence and also monitoring and operating tools like Opsgenie.
In the Jira tool, you can build a roadmap that is connected with the project work and it enables you to sketch a longer-term view of the work also to share and track the progress of the roadmap.
Jenkins – Jenkins is an open-source automation tool that is used to build and test the product, so the developers can continuously integrate changes into the build as well as it provides continuous integration and continuous delivery of projects. Jenkins provides various plugins to support building, deploying, and automating any work project.
Jenkins can be utilized as a simple CI server as well as can be changed into a continuous delivery hub for any ongoing project. Jenkins is a self-reliant java-based program and comes to run with packages for Windows, Linux, macOS, and other UNIX-like operating systems.
Jenkins can distribute the work in various machines, helping drive builds, tests, and faster deployment over various platforms.
New relic – New relic is a tool that focuses on performance and availability monitoring. It helps in tracking the performance of distributed apps and services.
New relic helps SRE’s create and monitor custom data sets.
Kubernetes – Kubernetes is the modern method to automate Linux container operations. Kubernetes helps in easily and efficiently managing clusters that run Linux containers over public, private, or hybrid clouds.
Kubernetes is an open-source tool that “containerizes” work pressures, manages deployment and configurations. Kubernetes maintains by the Cloud Native Computing Foundation.
Kubernetes can automatically make changes in the configuration of deployed containers or even deploy new containers based on metrics it tracks or requests made by engineers. Handling these processes through Kubernetes saves time, eliminates hard work, increases consistency. Kubernetes allows the creation of custom resources based on specific applications.
In Kubernetes, the Operator can be able to alter the configuration and usage of an application based on the application’s output. SRE tools always invest in reliability.
Terraform – Terraform is an infrastructure as code tool that permits to build, and change infrastructure. It comprises low-level components such as compute instances, storage, and networking, as well as high-level components such as DNS entries, SaaS features, etc.
Terraform can handle existing service providers as well as custom in-house solutions.
Terraform generates a plan that defines what its plan to do and asks for your approval before making any infrastructure changes, this process allows you to review changes before Terraform creates, updates or destroys infrastructure.
Terraform build a resource graph and modifies non-dependent resources in parallel. This allows Terraform to build resources and gives you greater insight into your infrastructure.
Terraform allows us to use a common configuration language to interact with different cloud providers. Terraform focuses on immutability, which is better for cloud, or hybrid environments.
Terraform assist several cloud infrastructure providers such as AWS, IBM Cloud (formerly Bluemix), Google Cloud Platform, Linode, Microsoft Azure, Oracle Cloud Infrastructure, and many more.
Ansible – Ansible is an open-source configuration management tool and Somewhere it functions like terraform but still, there are some differences between both.
Ansible is more focused on mutability, where resources can be changed rather than destroyed.
Ansible merges workflow orchestration with configuration management, provisioning, and application deployment in an easy-to-utilize and deploys platform. Ansible is for automating repetitive tasks, running infrastructure at scale, and increasing deployment frequency.
Building a CI/CD pipeline needs buy-in from numerous teams. It can’t be done without a simple automation platform that everyone in an organization can use. Ansible Playbooks keeps applications properly deployed and managed in the entire lifecycle.
Configurations can’t define your environment alone. You need to define how multiple configurations interact and make sure the disparate pieces can be managed as a whole. Out of difficulty and chaos, Ansible brings order.
When it comes to defining your application with Ansible and managing the deployment with Ansible Tower, teams can manage the entire application lifecycle from development to production.
Network implementations and alterations are no longer being done manually on the network hardware itself, but automating the process to reduce human mistakes and hard work.
Datadog – Datadog functions as cloud monitoring. Datadog can be used to view existing infrastructure hosts, collect events, and many more as well as datadog features to customize integrate the solution with other systems.
Datadog Application Performance Monitoring offers end-to-end distributed tracing from frontend devices to databases. By seamlessly associating distributed traces with frontend and backend data, Datadog APM allows you to monitor service dependencies, decrease latency, and eliminate errors so your users get the best experience.
Datadog supports organizations that encourage a culture of observability, collaboration, and data-sharing, all of that are key pillars of the DevOps movement.
DevOps is a culture and Datadog is part of the authorization of that process by permitting different parts of the business to interact with a common observability platform.
