You must have a thorough understanding of continuous delivery (CD) theory, ideas, and their practical implementation if you want to succeed in this position. In order to combine various tools and systems to develop fully functional, coherent delivery pipelines, you will not only need experience with CD technologies and systems but also comprehensive understanding of their inner workings. The software release process involves committing, merging, building, testing, packaging, and releasing code, among other activities.
You must be familiar with AWS CodeDeploy, AWS CodeBuild, and AWS CodePipeline if you plan to use the native AWS services for your continuous delivery pipelines. You may also need to be familiar with GitHub, Jenkins, GitLab, Spinnaker, Travis, and other CD tools and systems.
An AWS DevOps engineer should be knowledgeable about AWS services, resources, and best practices. Product development teams will contact you with inquiries about different services as well as requests for advice on which service to employ and when. As a result, you ought to be well-versed in the wide range of AWS services, their limits, and other (non-AWS) solutions that might be more appropriate in particular circumstances.
You will architect and develop cloud native systems, manage the complexity of cloud systems, and make sure that best practices are followed when leveraging a wide range of cloud service providers thanks to your knowledge of cloud computing. When planning and making recommendations, you'll also consider the advantages and disadvantages of adopting IaaS services versus PaaS and other managed services.
Oh my, monitoring, alerting, and logging! It's fantastic to ship a new application to production, but it's even better if you understand what it does. Observability is a crucial area of work for this function. The implementation of proper monitoring, logging, and alerting solutions for an application and the platforms it runs on is the responsibility of an AWS DevOps engineer. Application performance monitoring, or APM, can make debugging custom code easier and reveal important insights into an application's inner workings. New Relic, AppDynamics, Dynatrace, and other APM tools are available. You need to be very familiar with Amazon CloudWatch (including CloudWatch Agent, CloudWatch Logs, CloudWatch Alarms, and CloudWatch Events), AWS X-Ray, Amazon SNS, Amazon Elasticsearch Service, and Kibana on the AWS side. Additional devices and programs that you could use Syslog, logrotate, Logstash, Filebeat, Nagios, InfluxDB, Prometheus, and Grafana are among the tools that are used in this area.
AWS DevOps Engineers use Infrastructure as Code (IaC) tools like CloudFormation, Terraform, Pulumi, and AWS CDK to ensure that the systems they are responsible for are developed in a repeatable manner (Cloud Development Kit). By utilising IaC, cloud objects are guaranteed to be code-documented, version-controlled, and capable of being reliably replaced using the right IaC provisioning tool.
Once EC2 instances have been launched as part of IaaS (Infrastructure as a Service) for virtual machines, a Configuration Management tool should be used to record their configuration and setup. Ansible, Chef, Puppet, and SaltStack are a few of the more well-liked alternatives in this field. Powershell Desired State Configuration (DSC) may be the best tool for this task in enterprises where Windows is the infrastructure of choice.
Many contemporary enterprises are switching from the conventional deployment methodologies of pushing software to VMs to a containerized system environment. Configuration management loses a lot of importance in the containerized environment, but you'll also need to be conversant with a whole new set of container-related technologies. These tools include Kubernetes (which has a large ecosystem of tools, apps, and services), Docker Engine, Docker Swarm, systemd-nspawn, LXC, container registries, and many others.
Logging, monitoring, and alerting are the most frequently mentioned components of IT operations. To effectively operate, run, or manage production systems, you must have these things in place. These were discussed in the observability section up top. Responding to, debugging, and resolving problems as they arise is a significant aspect of the Ops function. You must have experience working with and troubleshooting operating systems including Ubuntu, CentOS, Amazon Linux, RedHat Enterprise Linux, and Windows if you want to respond to problems quickly and efficiently. Additionally, you'll need to be knowledgeable about middleware tools like load balancers, various application environments, and runtimes, as well as web servers like Apache, nginx, Tomcat, and Node.js.
An essential role for a database manager might also be database administration.(Dev)Ops position You'll need to be familiar with data stores like PostgreSQL and MySQL to succeed here. Additionally, you should be able to read and write a little SQL code. You should also be more familiar with NoSQL data stores like Cassandra, MongoDB, AWS DynamoDB, and perhaps even one or more graph databases.
The site reliability engineer's purpose is to eliminate labor, and the DevOps engineer's mission is also extremely appropriate. You'll need knowledge and proficiency with scripting languages like bash, GNU utilities, Python, JavaScript, and PowerShell on the Windows side in your desire to automate everything. Cron, AWS Lambda (the serverless functions service), CloudWatch Events, SNS, and other terms should be familiar to you.
The cultural aspect of DevOps is last, but certainly not least. Even while the word "DevOps" can represent a variety of things to a variety of people, CAMS—culture, automation, measurement, and sharing—is one of the greatest places to start when discussing this change in our industry. The main goal of DevOps is to eliminate barriers between IT operations and development. Developers no longer "throw code over the wall" to operations in the new DevOps era. With everyone playing a part in the success of the code, the applications, and the value being provided to consumers, we now want to be one big happy family. As a result, software developers and (Dev)Ops engineers must collaborate closely. The ability to collaborate and communicate effectively is required for any candidate for the essential position of a DevOps engineer.
You need a blend of inborn soft skills and technical expertise to be successful in the DevOps job path. Together, these two essential characteristics support your development. Your technical expertise will enable you to build a DevOps system that is incredibly productive. Soft skills, on the other hand, will enable you to deliver the highest level of client satisfaction.
With the help of Great Learning's cloud computing courses, you may advance your skills and land the job of your dreams by learning DevOps and other similar topics.
If you are brand-new to the DevOps industry, the list of required skills may appear overwhelming to you. However, these are the main DevOps engineer abilities that employers are searching for, so mastering them will give your CV a strong advantage. We hope that this post was able to provide some clarity regarding the DevOps abilities necessary to develop a lucrative career.
