It is impossible to ignore the buzzword ‘k8s’ in the world of application deployment and management. Kubernetes has become interchangeable with ‘containers,’ much to how people now say ‘Google’ rather than ‘internet search.’ Why? Because Kubernetes is great at what it is made for – container orchestration and there are no legit rivals to it. With that being said, is Kubernetes alone enough to run containerized applications?
No, in order to derive the brimming potential of the open-source system, you need a uniquely crafted operational framework for leveraging Kubernetes to its fullest. This brings us to Avasoft’s ‘KubeOps’ approach that results in better and upgraded Kubernetes operations!
What is ‘KubeOps?’
The Key Factors of KubeOps Framework:
Think Kubernetes but better and you will land on Avasoft’s KubeOps. Our framework amplifies the operational efficiencies of Kubernetes by enhancing its existing features as well as by adding efficient operational methods. It drastically minimizes the complex aspects of Kubernetes through a well-architected framework. Our KubeOps practice supports everything from installation to monitoring of the application. It also addresses security, distribution, and production, resulting in holistic K8s usage.
Increasing the volume of the rollouts quickly is one of the major hurdles in today’s cloud-native application development. In a bid to help organizations lessen the risk, it is crucial to select the best deployment approaches that our KubeOps framework has to offer.
The following table defines the diverse deployment strategies:
Abort the old version and deploy the new one
Deploy a new version one after the other periodically
Blue/Green (most efficient and adaptable)
Deploy both the updated version and the older one before shifting traffic
Test two versions of the same application
Test two versions of the same application based on specific parameters
You most likely have an understanding of the deployment strategies now. Bring in your thoughts, let’s brainstorm and find the best deployment strategy for your organizational model or business requirements!
Service mesh sits on top of your Kubernetes architecture, enabling secure and dependable network interactions between services. It allows development teams to engage more in the application logic while lowering the burden of microservice implementations. It also controls the flow of data between services.
The following are the advantages offered by service mesh:
Helps different services communicate with each other
Aids in expanding the many versions of services autonomously
Durability mechanisms are placed so that one service failure won’t shut down the entire workflow
Determine how services communicate, how much time they take to complete specific activities, and, if an issue occurs, identify its foundation
Helps in figuring out the general application performance
Offers verification, restriction, and encryption
Your Pods are automatically assigned to Nodes with sufficient capacity by the Kubernetes scheduler. Occasionally, regardless of its great attempts, the scheduler won’t choose a plan you are happy with. With the help of our KubeOps framework various spike implementation techniques, you can direct the scheduler’s choices such that Pods land on certain Nodes according to your demands. This way, you can fine-tune the allocation as well as:
Multiple interconnected Kubernetes resources, including pods, services, deployments, and replicasets, have to be created in order to build a single application. Each of these resources require you to produce a comprehensive package manager. Helm is a Kubernetes package manager that facilitates developers and administrators to organize, set up, and launch applications and services into Kubernetes clusters.
Helm comes with a lot of functionalities such as:
The monitoring function of Kubernetes aids in the proactive maintenance of clusters, nodes, and pods. By keeping track of all three, our KubeOps framework makes managing containerized infrastructure easier.
The three primary types of Kubernetes monitoring are as follows:
Monitors the entire cluster
Monitors certain cluster nodes
Monitors the lifecycle of certain pods inside the cluster
Furthermore, there are three crucial indicators to keep an eye on in Kubernetes:
CPU, memory, and storage are monitored for availability. This information is crucial for maintaining the stability of the cluster and the efficiency of the K8s-based applications.
Cluster State Metrics
Information on the quality and functionality of KubeOps components, such as pods and deployments, cluster state metrics are provided.
Control Pane Metrics
The API server, controller managers, schedulers, etcd, and other essential control plane elements are all covered in the control plane indicators. This is vital for cluster management.
When implemented early in the design process, logging assists in bug diagnosis, provides insight into system behavior, and identifies prospective problems before they arise. But how can logs be gathered in infrastructure running on a container orchestration system? The answer is either ELK Stack, Graylog, or Filebeat.
Elasticsearch, Logstash, and Kibana are three open-source tools that collectively make up the term “ELK stack.”
A full-text search and analytics engine
Log aggregator that gathers, transforms, and distributes data to a variety of locations, including Elasticsearch
Offers a user interface that enables users to query, display, and evaluate their data using graphs and charts
Supervision, debugging, web analytics, risk assessment, business analytics, compliance, fraud prevention, and security assessments are some of the most typical ELK use cases.
Graylog is a powerful log management solution that gathers, explores, and presents insightful log data in a dynamic online interface. It gathers information from both Kubernetes clusters and from single or several servers. Here is everything it has to offer:
Collection – Log data is gathered and presented in a user-friendly and engaging visual interface.
Analysis – Makes it simpler to comprehend and analyze the log data that has been gathered.
Configuration – A variety of data types are supported, and can be set up to email log notifications.
Filebeat simplifies gathering, processing, and visualizing popular log sources with one command. It does it by integrating and operating system-based automated default pathways. To guarantee that a version of Filebeat is operating on each cluster node, it is launched as a DaemonSet.
The following choices exist for establishing Filebeat DaemonSet to gather Kubernetes logs from the cluster:
Some of the advantages Filebeat has to offer:
Forward and centralize logs and files easily
Quickly ship higher volumes of data
Any kind of vulnerability or attack might give restricted access to an outsider of the company. To prevent this, you can set up a policy in Kubernetes that prohibits users from deleting pods using RBAC. Utilizing Kubernetes RBAC will limit what certain users can change within your cluster. By giving them the responsibilities that are suitable for their jobs, you can mix or combine roles to offer them the access you desire.
Some examples of policies that can be placed using RBAC include:
