DevOps refers to an organization's combination of tools and practices, which is aimed at increasing applications, software and service delivery. The model incorporates the software development and information technology operations teams together to work as one synchronized unit. This is also where the DevOps name is derived from. Throughout the application development lifecycle, therefore, the teams are able to function in a manner that promotes fast and easy development, security and quality assurance. DevOps limits downtime that would normally occur during the phases of each stage of the application's lifecycle, such as between development and testing. More so, using numerous DevOps tools, the teams are able to automate processes that would normally be manual, which increases efficiency and cuts down on time and resources used through the development process.
DevOps evolved from agile software development, which refers to techniques used to ensure there was collaboration in the individual efforts of different development teams as expressed in the Agile Manifesto. DevOps evolved to further improve the agile methodology and guarantee greater efficiency and easier communication between the teams throughout each stage of development.
The DevOps lifecycle is centered around ensuring that there are little downtime and constrictions between the phases of development to guarantee continuous delivery. As such, it employs techniques of continuous integration (CI), continuous testing (CT), continuous delivery (CD) or deployment and continuous monitoring. Through each phase, the automated process reduces the amount of time taken for each team to understand the code and pass it along the chain, which reduces the amount of time spent before the software is rolled out to the market. The steps of the DevOps Lifecycle include:
Testing and debugging
Introduction To Agile Methodology
Agile Methodology refers to techniques used by developers to work as teams and cooperating with the customer to increase their efficiency in development. This is all based on principles listed in the Agile Manifesto that underline what should be done in Agile software development. The methodology aims to shift from traditional software development where the emphasis was on individual effort without customer input, leading to slow and expensive development.
How DevOps Appreciates Agile Methodology
Having evolved from Agile Software Development, there are instances where DevOps borrows from and appreciates the Agile Methodology even though both are different philosophies of development.
Customer/ End-user involvement
By integrating the operations teams throughout the entire process of development, DevOps guarantees constant end-user involvement and input in the product. This is one of the ideologies borrowed from Agile Methodology that makes the product more effective as it is released at each stage of development.
Although Agile Methodology focuses on unifying development teams to work as a single unit, this philosophy is a major influence of how DevOps functions. DevOps unifies the development and operations teams to work together to achieve faster, affordable, efficient and effective software delivery to the customer.
Introduction to various DevOps Tools
Version control systems (VCS) refer to software systems that are used in the tracking and management of changes to files/documents, programs, websites and other information. Though they are normally run as independent systems, they can also be embedded and operated as part of other software and systems such as spreadsheets, content management systems, among others. Examples include Git, Subversion, AccuRev, among others.
Continuous Integration (CI) refers to the practice where a developer updates or uploads new code into a shared repository regularly, usually several times daily, where other developers in various development teams have access to it. This allows for early and easy detection of code integration problems, enabling quick and targeted rectification. The shared repository, in this case, is a VCS, which can track the changes to the code.
The development process may include a high number of developers using the same tools and resources and deploying code components to the same product. A VCS is used to track and manage the changes to these shared tools, resources and product for the eventuality of building all the source files into binary artifacts. An artifact repository manager is used to ensure optimal storage, upload, and download of these binary artifacts as well as any third party artifacts used by the developers, including the metadata. This reduces branching and complex diversity that would otherwise arise from using different artifacts in the development of the same software. An example is Maven.
Continuous deployment tools
After successful continuous delivery, there needs to be continuous deployment, which automatically deploys all the changes in the software that pass the automated tests to production. Continuous deployment is an automated process that relies on tools, which run the tests and deploy the code, such as ElectricFlow, Octopus Deploy, Codeship, among others.
Continuous monitoring tools allow for the early detection and identification of risks and compliance in various systems throughout the entire development process to limit the problems encountered and are grouped into categories as follows:
Network and infrastructure monitoring tools
These tools are responsible for monitoring, identifying and resolving problems in the infrastructure and network, such as the servers and routers. Examples include Zabbix, Sensu, Nagios, among others.
Application performance monitoring tools
These tools help monitor the health and performance, provide early detection and help resolve problems, improve performance, reduce latency and enable troubleshooting for your applications. Examples include Compuware APM, AppDynamics, New Relic, among others.
Log analysis tools
These tools allow for the indexing and monitoring of log files, which provides security monitoring. Examples include Elastic Stack, Splunk, among others.
These tools provide integration and monitoring of other monitoring tools providing correlations between events in Network and infrastructure, application performance, and log files, easy user interfaces, and alerts. Examples include PagerDuty, BigPanda, among others.
GitFollowing issues in accessibility, performance and workflow with BitKeeper, Monotone and all other accessible Source control management systems at the time, it became necessary for the development of a system that accommodated for all these issues and provided all the necessary functions. Which is how Linus Torvalds, began the development of Git. Based on the Linux Kernel, it is an open source, free VCS with high portability, integration, and compatibility, security, performance as well as efficiency in both small and large projects.
Continuous IntegrationIntroduction to continuous integration and various CI tools
As earlier defined, Continuous Integration (CI) refers to the practice where a developer updates or uploads new code into a shared repository regularly, usually several times daily, where other developers in various development teams have access to it. Various practices make continuous integration an achievable objective and these include:
Using an artifact repository
This allows the developers to work as a comprehensive unit, limiting the chance of different branches of code arising. More so, you can use VCS and artifact repository management tools to better store, track, identify and act on the changes made in the code.
When it comes to building, testing, and deployment, you should automated processes. This allows for a fast and easy build, immediate self-testing and fast deployment. Automation also limits the need for human input, which reduces chances of mistakes and slow pace. This also enables every developer's code to be built, which limits issues arising from incorrect integration. Various tools can be used in each of these phases of the development lifecycle.
Everyone involved in the development process should have unlimited access to the repositories to see the changes, upload and download data and other functions. More so, this should go hand in hand with ensuring that each developer contributes to the code on a daily basis, which limits the rise of conflicting or redundant code and features.
Using a production environment
Instead of using a test environment, carry out tests in a production environment, reducing the need to run the checks again, making production fast. Most importantly, differences in the test and production environment could lead to failures in the production environment even though the code works in the test environment. Your test environment should, therefore, be a scalable copy of the production environment.
All these practices can be made easier and more effective through the use of continuous integration tools such as Jenkins, Codeship, Travis CI, TeamCity, GitLab CI, CircleCI, among others.
Jenkins is an open source continuous integration tool that runs on the Java SE platform. It's installed on the same server that the build takes place and is distributed as a WAR file.

JIRA (Bug Tracking Tool)
JIRA is a Java-based tracking tool used in issue tracking, bug tracking, and project management during the DevOps development process.
Introduction to Developer Role
Throughout the process of development, JIRA allows different users to be assigned different project roles, allowing greater control of the project and over who can access what information. These roles include Administrator roles, developer roles, and user roles. The developer role is assigned to individuals with the responsibilities of working on the project and its issues. You can also create new roles and edit new and existing roles as the need arises.
Introduction to Artifacts and various artifact repository tools
In the development process, there are many by-products produced with different functions. One such function is the documentation of the development process and functions of the different software, architecture and other resources. Another function is the development process such as in the case of risk assessments, project plans, among other functions. These by-products are known as artifacts. An artifact repository manager/ tool, as earlier mentioned, is used to ensure optimal storage, upload, and download of these binary artifacts as well as any third party artifacts used by the developers, including the metadata. Examples of artifact repository tools include Nexus, Archiva, Maven Repository, among others.
The Nexus artifact repository tool allows for the cataloging of artifacts preceding storage. Multiple artifact catalogs can be created allowing for efficiency in that different teams can store their artifacts in the same repository and call them up using the different catalogs.

Demo on spinning up an instance in AWS and connect it from your desktop
Before you can connect to an ECS instance, you have to launch. There are different types of instances so you have to know, which instance you are launching such as a Linux or Windows Instances or an instance launched through the AWS CLI. Just as there are various ways to launch an instance, there are also different ways of connecting to the instance such as through a web browser for a Linux Instance and using a Remote Desktop Protocol (RDP) or the IPv6 for a windows instance. For detailed information on how to launch and connect to the instance follow the following links:
Create security groups in AWS and setting up firewall rules in AWS
Security groups are virtual firewalls that control network traffic in one or multiple instances. The flow of traffic in and out of the instance as controlled by the security groups is defined by the security group rules, which are by default permissive, stateful and allow outbound traffic in the instance. You can modify the rules at will. Multiple security groups can be associated with an instance and the rules applied in each security group will be combined to create a single set of rules. To set up the security group rules, you have to define the following variables from their default options:
ICMP code and type
Either the destination or source of network traffic
For detailed information on security groups and security rules, visit the following link: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html
Introduction to continuous deployment
Continuous Deployment comes after Continuous Delivery in the development process following DevOps techniques. Using automated processes and tools, any changes in the software are tested and if they successfully pass the tests, they are deployed to production. This reduces lead time and the effort used in the deployment of the software.
Introduction to various deployment toolsChef
Chef Development Kit
This acts as the workstation, providing the developer with tools for development and automation before deployment.
This acts as the repository for information about the nodes that are under its management and the state of infrastructure.
These are virtual or physical machines under the management of the chef server but in use by the client or customer.
