海外TECH	DEV Community	#1 What's Site Reliability Engineering [SRE] | Roles & Responsibilities | Technologies involved	https://dev.to/developertharun/1-whats-site-reliability-engineering-sre-roles-responsibilities-technologies-involved-1dcc	What x s Site Reliability Engineering SRE Roles amp Responsibilities Technologies involved Site reliability engineeringSite Reliability Engineering also popularly referred to as the SRE is a role in Computer Science Engineering where the main purpose is to provision maintain monitor and manage the infrastructure in order to provide maximum application uptime and reliability SRE is an emerging role but the tasks that the SRE does were always there ever since the first application that was developed The scope of the software developers ends where they write code to develop the application and right from setting up the infrastructure the various services that run on them the network connectivity that is required providing a platform for the application to run and making sure every part of the application is up and running reliably x is the duty of an SRE In fact we can consider Site Reliability Engineers are the strong bridge between the users and a reliable application Now in order to explain the different responsibilities of an SRE I have divided it into different categories I have always seen SRE this way and definitely not as some ad hoc process The four categories in which I would classify the tasks of a Site Reliability Engineer are CreateMonitorManageDestroyLet s dive deep into each one of them Create Provision virtual machines PXE BaremetalsSREs are responsible for provisioning the virtual machines with the requested resources in terms of CPU memory disks network configurations and operating system In case a bare metal needs to be set up it is also performed with the provided configurations The SREs use Linux commands automation scripts to provision the server as quickly as possible They are also responsible to be rack aware during provisioning Example operating systems involve Linux Ubuntu CentOS Windows Setup servicesOnce the machines are provisioned the SRE also takes care of setting up the services on the machines These services can be networking services proxy or load balancing services container or orchestration services message queues databases caching systems big data services or more along with the disk setup In this way the SRE are exposed to a variety of technology and play an important role in the components involved in an application Example technologies involve NGINX Apache RabbitMQ Kafka Hadoop Traefik MySQL PostgreSQL Aerospike MongoDB Redis MinIO Kubernetes Apache Mesos Marathon MariaDB Galera Optimize the infrastructureSince there are several components and services that are being used in the infrastructure there is a scope for improvements in terms of performance efficiency and security The SRE optimizes the components by keeping them up to date choosing the right service for the right job patching the servers Write monitoring scriptsWhen the SRE are involved in maintaining an infrastructure of any size they never underestimate any component of the infrastructure and write a monitoring script to monitor the components and metrics of each and every one of them This provides the ability to get real time alerts on any of the components malfunctioning and also a better view of the infrastructure The SRE uses programming languages like Bash Python Golang Perl and tools like daemon processes Riemann InfluxDB OpenTSDB Kafka Grafana Prometheus and APIs to monitor the infrastructure Write automation scriptsIf there are more than steps to be performed and chances are that the task has to be performed more than once the SRE never hesitate to automate the task This saves time and also prevents human error The SRE uses programming languages like Bash Python Golang Perl Ansible to automate the tasks Manage users on the machinesOne of the main security precaution that the SRE take is to restrict user access to the components in the infrastructure They use various technologies like VPN Virtual Private Network firewall configuration files user management on machines LDAP sudoer configuration PAM OTP two factor authentications SSH keys and more to avoid unauthorized access to any component of the infrastructure These are the create aspects of a Site Reliability Engineer In the next article we will read about the Monitor aspect of a Site Reliability Engineer Complete Video Watch the video above or listen to the full podcast exclusively below Podcast You can find more articles here Thank youCheck out my YouTube Channel here Developer Tharun YouTube Thank you for reading	2022-01-08 12:30:04
