Today, @ Poshem Technologies Institute we covered essential topics in Azure DevOps, focusing on branches, pull requests, and merges. We learned that branches allow us to work on features or fixes separately from the main codebase. We created a new branch locally, committed changes, and pushed it to the Azure Repo. We also worked on Pull requests (PRs) which ensure that no branch can be merged into the main branch without meeting specific conditions and receiving approvals. We set up branch policies to require two reviewers for each Pull request before merging. We then initiated, reviewed, approved, and completed the merge, deleted the branch, and pulled the latest changes to our local repository. We explored different types of merges. Fast forward merge which is a direct linear path merge when no other changes have been made to the main branch. We also touched A three-way merge which combines changes from three branches: the current branch, the target branch, and their common ancestor. We also practiced using several Git commands. Git log shows commit history. Git revert undoes changes from previous commits with a new commit. Git reset resets the current HEAD to a specified state. Git squash combines multiple commits into one. Git cherry-picking applies changes from specific commits to another branch. It was a great session where we learned to manage code changes and collaboration effectively. #AzureDevOps #DevOps #Git #SoftwareDevelopment #Programming #Tech #Coding #SoftwareEngineering #VersionControl #Collaboration #Agile #CloudComputing #TechCommunity #ContinuousIntegration #ContinuousDelivery #Azure

🔧 Are you harnessing the power of gRPC interceptors for your application's performance and security? A recent Medium article by Ahmet T. Soner delves into how gRPC interceptors can transform your services by adding layers of functionality without compromising core business logic. Whether you're dealing with unary or streaming RPCs, interceptors serve as middleware-like components to streamline processes. Here's why this matters: - **Centralized Cross-Cutting Concerns**: Implement logging, caching, and authentication consistently across your services, improving both performance and maintainability. - **Enhanced Security**: Bolster your security protocols by embedding authentication and authorization checks seamlessly into your gRPC calls. - **Performance Insights**: Learn to measure and mitigate the performance overhead that interceptors might introduce, ensuring that your applications remain fast and responsive. For a deep dive into their implementation across different programming languages and strategies to optimize their usage, check out the article [here](https://lnkd.in/dGesnkFa). 📢 **Call to Action**: Have you implemented gRPC interceptors in your projects?

A Visual Overview of Kubernetes Kubernetes is an open-source container orchestration platform that helps deploy, scale, and manage containerized applications across clusters of machines. It addresses the challenges of running containers at scale. 𝗖𝗼𝗿𝗲 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 𝗖𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀 Control Plane: The cluster management system, handling scheduling, maintaining desired state, and rolling updates. Runs on multiple machines for high availability. Worker Nodes: Machines running containerized applications. Each node contains components like kubelet and kube-proxy alongside application containers. Pods: The smallest deployable units in Kubernetes, encapsulating one or more tightly coupled containers. 𝗧𝗿𝗮𝗱𝗲𝗼𝗳𝗳𝘀 Kubernetes offers powerful features but comes with complexity. Its steep learning curve can be challenging for teams. Managed Kubernetes services can help by handling control plane management. 𝗜𝘀 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 𝗮 𝗚𝗼𝗼𝗱 𝗙𝗶𝘁? Consider: - Are you running containers at a meaningful scale? - Will improved portability or resiliency resolve production issues? - Is your team prepared to invest in learning and operating Kubernetes? If you answered yes to these questions, Kubernetes may suit your needs. Otherwise, simpler container solutions might suffice.

Zabbix is a powerful open-source monitoring solution designed to track the health and performance of various IT components, such as networks, servers, virtual machines, applications, and services. It’s particularly popular in IT operations due to its versatility and ability to scale for monitoring environments of all sizes. Zabbix Dashboard: The Zabbix Dashboard is the central hub for monitoring data and provides a highly customizable visual representation of monitored components. The dashboard offers: Widgets: It supports various widgets, such as graphs, maps, screens, triggers, problems, and top hosts. Widgets are customizable to display specific metrics or information about monitored entities. Problem View: This view lists current issues with details on the severity, duration, affected host, and trigger, helping administrators to prioritize and address problems quickly. Triggers and Events: Zabbix allows you to configure triggers to identify when a metric exceeds predefined thresholds. Triggered events appear on the dashboard to notify users in real-time. Custom Views: Users can personalize the layout and contents of the dashboard based on their monitoring requirements. This can include summary screens, reports, maps, and critical data visualizations. Heat Maps: Zabbix’s heat map widget visually represents host statuses, making it easy to identify problematic hosts at a glance. User Permissions: Access can be controlled based on user roles, allowing for secure, multi-user access to different parts of the dashboard.

I explain and express everything in terms of Spring Boot (Java) because it is the programming language I am most exposed to and enjoy working with. I am continuously learning more and applying my knowledge to projects, as Spring Boot is broad and evolves every six months with new features and bug fixes. Microservice A microservice in Spring Boot refers to a small, independently deployable service that focuses on a specific business functionality. Spring Boot is a popular framework for building microservices because it simplifies the setup and development process. It has good key characteristics and benefits of microservices in Spring Boot. Integration In software development, integration refers to combining various components, systems, or software applications into a single, cohesive system to ensure they work together effectively. Integration is crucial for creating complex systems where different parts must interact seamlessly to provide the desired functionality and there are types, benefits, and Tools & Technologies of Integration. API In Spring Boot, an API (Application Programming Interface) refers to a set of endpoints exposed by a Spring Boot application to allow other applications or clients (like web browsers, mobile apps, or other servers) to interact with it. These APIs are typically built using REST (Representational State Transfer) principles, though they can also be based on other protocols like SOAP or GraphQL. APIs in Spring Boot provide a powerful and flexible way to expose the functionality of your application to other systems and clients. By using Spring Boot’s features and annotations, you can quickly create RESTful endpoints that are easy to maintain and extend. Spring Security It's a powerful and customizable authentication and access-control framework for Java applications. It is a part of the larger Spring ecosystem and is designed to handle the security requirements of enterprise-level applications, including both web and non-web applications. Spring Security provides comprehensive security services for Java EE-based enterprise software applications, leveraging the simplicity and power of the Spring framework. Software Deployment Deployment of a Spring Boot application involves packaging your application and making it available on a server or cloud environment where it can be accessed and run by users or other systems. The process includes various steps from building the application to configuring the environment and managing the deployment artifacts. Deploying a Spring Boot application involves building the application, choosing the appropriate deployment environment, configuring environment-specific settings, and managing the deployment artifacts. Spring Boot’s flexibility allows for easy deployment across various platforms, from local servers and dedicated application servers to cloud platforms and containerized environments. #SystemDevelopment #javaDeveloper #BackEndDeveloper #DevOpsEngineer
