An Introduction To DevOps Processes and Their Significance


In traditional software development methodologies, the time taken for code deployment was a major setback. One of the main reasons for slower code deployment was the lack of consistency between the development and the operations teams. To bridge this gap, the concept of DevOps came into action.

DevOps solutions and services provide continuous monitoring and integration of the tasks being performed by development and operations teams. It brings developers and operations experts under the same roof to improve the efficiency of IT processes. DevOps is increasingly becoming popular amongst IT companies because it helps them effectively meet the dynamic requirements of the IT infrastructure.

What Is DevOps?

DevOps is a software development strategy that bridges the gap between the development and operations teams. It is a set of practices that works to automate and integrate the processes between software development and IT infrastructure management. As a result, it streamlines the entire workflow so they can build, test, and release software faster and more reliably.
 

How It works?

DevOps is a philosophy that involves both development and operations teams to work together throughout the project development lifecycle. From product design to its release and support, DevOps ensures accelerated processes with a focus on continuous delivery and continuous integration. It unites several effective tools like Agile, Git, Gradle, Jenkins, and more to accelerate the software development lifecycle and reduce time-to-market. 

Let’s discuss DevOps processes and explore the DevOps roadmap in detail through the following stages:

Planning

This is the first stage where the DevOps teams discuss the project goals and requirements with their clients and formulate an execution strategy.

Coding

Once the plan is finalized, the programmers can design and code the application. With tools like Git, developers have a repository to store all the codes and their different versions. It helps them work on the same codebase rather than working on bits of code for different operations.

Build

In this stage, the codes from different repositories are combined to build the complete application. Tools like Maven and Gradle enable developers to execute this process.

Testing

Before its deployment, the application is tested using automation tools like Selenium and JUnit to detect and fix bugs that are essential to ensure software quality.

Integration

It is the core of the DevOps working cycle that makes this methodology so effective. Tools such as Jenkins enable developers in the process of sending the codes for building and testing. When the testing is complete, it is further sent for deployment. This process is called continuous integration.

Deployment

In this stage, the application is packaged after release and deployed from the development server to the production server.

Operation

Once it is successfully deployed, the operations team configures the servers, provisioning them with the required resources. Tools such as Chef, Docker, and Ansible are effective at operating and managing various productions.

Monitoring

Every product is continuously monitored in its own working environment. Continuous monitoring enables IT companies to identify specific issues with various releases. It helps them understand the impact of their product on end-users, thus providing the best possible solution for each client.

Benefits

Collaboration and Trust

It is one of the most important elements of the DevOps culture as it brings both development and operation teams to work in collaboration. In doing so, they can establish a culture of shared responsibility, transparency, and faster feedback.

Improved Defect Detection

The development team designs and develops each block of functionality of an application. Then the application is immediately tested and taken over by the operations team for finalizing the deployment process. Working cohesively makes it easier to detect any loopholes that may arise in the process and to increase the stability of the platform.
 

Accelerate Time to Resolution

DevOps teams are equipped with fully transparent and seamless modes of communication. As a result, they are able to resolve critical issues in less time without any frustration between the development and operations teams. DevOps teams can discuss the issues freely, fix the bugs, and solve the matters faster and more efficiently.
 

Increased Effectiveness

DevOps offers a combination of several tools and effective practices that enables IT companies to automate testing, deployments, and provisioning of services. It lets them reduce repetitive tasks and allows them to focus on their core operations. At the same time, it ensures higher productivity at work and aids in delivering higher quality outputs.

An Introduction To Kafka Architecture and Kafka as a Service

Kafka and Kafka as a Service

Apache Kafka is a fast and scalable Publish/Subscribe messaging platform. It enables the communication between producers and consumers using messaging-based topics. It allows producers to write records into Kafka that can be read by one or more consumers per consumer group. It's becoming a solution for big data and microservices applications. It is being used by several companies to solve the problem of real-time processing. AWS development services also render support for Apache Kafka via its fully managed Amazon MSK (Amazon Managed Streaming for Kafka) platform.

A Broker is like a Kafka server that runs in a Kafka Cluster. Kafka Brokers form a cluster. The Kafka Cluster consists of many Kafka Brokers on several servers. Brokers often refer to more of a logical system or as Kafka as a whole.

It uses ZooKeeper to manage the cluster. ZooKeeper is used to coordinate the brokers/cluster topology. ZooKeeper gets used for leadership elections for Broker Topic Partition Leaders.

The Kafka architecture consists of four main APIs on which Kafka runs.
  1. Producer API:
This API allows an application to publish a stream of records to one or more Kafka topics.

Consumer API

It allows an application to subscribe to one or more topics. It also allows the application to process the stream of records that are published to the topic(s).

Streams API

This streams API allows an application to act as a stream processor. The application consumes an input stream from one or more topics and produces an output stream to one or more output topics thereby transforming input streams to output streams.

Connector API

This connector API builds reusable producers and consumers that connect Kafka topics to applications and data systems.

Kafka Cluster Architecture


Kafka architecture can also be described as a cluster with different components. 

Kafka Broker

A Kafka cluster often consists of many brokers. One Kafka broker can be used to handle thousands of reads and writes per second. However, since brokers are stateless they use Zookeeper to maintain the cluster state.

Kafka ZooKeeper

This uses ZooKeeper to manage and coordinate Kafka brokers in the cluster. The ZooKeeper notifies the producers and consumers when a new broker enters the Kafka cluster or if a broker fails in the cluster. On being informed about the failure of a broker, the producer and consumer decide how to act and start coordinating with other active brokers. 

Kafka Producers

This component in the Kafka cluster architecture pushes the data to brokers. It sends messages to the broker at a speed that the broker can handle. Therefore, it doesn’t wait for acknowledgments from the broker. It can also search for and send messages to new brokers exactly when they start.

Kafka Consumers

Since brokers are stateless, Kafka consumers maintain the number of messages that have been consumed already and this can be achieved using the partition offset. The consumer remembers each message offset which is an assurance that it has consumed all the messages before it.

    volumes:

      - /var/run/docker.sock:/var/run/docker.sock

      - kafka_data/502:/kafka

Start The Cluster

Simply start the cluster using the docker-compose command from the current directory:
$ docker-compose up -d

We can quickly check which nodes are part of the cluster by running a command against zookeeper:
$ docker-compose exec zookeeper ./bin/zkCli.sh ls /brokers/ids

And that’s it. We’ve now configured a kafka cluster up and running. We can also test failover cases or other settings by simply bringing one kafka node down and seeing how the clients react.

Self-managed Kafka Services

We can also use Cloud-based self-managed kafka service on different cloud providers. cloud software development services provide fully managed and secure Apache Kafka service like Amazon MSK (Amazon Managed Streaming for Apache Kafka).

An Introduction To Amazon Managed Streaming For Apache Kafka


The popular video stream-processing software, Apache Kafka has gained significant traction over the recent years. The open-source tool that is mainly used for processing live streaming data, Kafka provides real-time analytics to derive maximum value from the streaming media content. Kafka has grown tremendously as many organizations have adopted this platform for building real-time data pipelines and video streaming applications. That being said, over one third of the fortune 500 companies use Kafka to run and manage their video streaming operations.

Seeing its increasing popularity, Amazon rendered its cloud support for Kafka to build and deploy applications that facilitate video stream processing. With the advent of Amazon MSK (Amazon Managed Streaming for Kafka), it has become easy to build and run real-time data pipelines and streaming applications. Amazon MSK also lets you populate various data lakes and stream variations from databases. Furthermore, you can use it to power machine learning algorithms and build applications with real-time analytics features.  


Challenges With Apache Kafka

Despite the many benefits, Apache Kafka clusters are not easy to set up, scale, and manage in the production environment. Developers must manually configure Kafka before they can run it. Additionally, it requires provision servers, in case your existing servers incur any unanticipated failure. 

Developers must orchestrate server patches, system upgrades, optimize clusters, and consistently manage scaling events to support load changes. Above all, developers need to ensure that data is securely stored for easy accessibility.  

How Amazon MSK Overcomes These Challenges

Amazon Managed Streaming for Kafka (MSK) enables developers to build and run streaming applications on Apache Kafka with ease. With Amazon MSK, they do not require expertise from Kafka infrastructure management services as Amazon renders complete support for building and deploying applications. As a result, developers can focus on the core development operations without getting into complexities of infrastructure management.
