Observability Done Right: Best Practices and Anti-Patterns for Effective System Monitoring

-
Image
  WHAT Observability is a concept that refers to the ability to gain insights into the behavior and performance of complex systems. In the context of software engineering, observability involves the collection, analysis, and visualization of data from software applications, infrastructure, and other components of a system. In the animal kingdom, observability plays a critical role in survival, allowing animals to monitor their surroundings, detect threats, and find food. Dolphins use echolocation to observe their surroundings. They emit high-frequency sounds that bounce off objects, allowing them to create a 3D map of their environment.

Unlocking the Potential of Your Web Application with a CDN

-
Image
  What is CDN A Content Delivery Network (CDN) plays an important role in application scaling by helping to distribute the load of an application across multiple servers in different geographic locations. This can help to improve the performance and availability of the application for users around the world. When a user requests a piece of content, the CDN will redirect the request to the server that is closest to the user, reducing the latency and improving the overall user experience. This is particularly important for applications that serve a large number of users or handle a high volume of traffic, as it can help to prevent any single server from becoming overwhelmed and causing the application to become unavailable. Additionally, CDN also helps to reduce the load on the origin server by caching frequently-requested content on the CDN’s edge servers. This can help to prevent the origin server from becoming a bottleneck and ensure that it is able to handle the traffic and reque...

Maximizing Efficiency with Spring Annotations: Best Practices and Tips

-
Image
  Annotation-Driven Development in Spring and Performance What is Annotation Driven Development Annotation-driven development is a programming paradigm that relies on the use of annotations to provide metadata about a class, method, or field. This metadata is then used by the framework or runtime environment to configure and manage dependencies, define transaction boundaries, map web requests, and more. In the context of the Spring framework, annotation-driven development refers to the use of annotations to configure and manage dependencies within the application. For example, instead of using XML configuration files to define beans and their properties, developers can use annotations such as @Component, @Service, and @Repository to define these beans and their properties directly in the code. How Annotation Works Here’s a brief overview of how Spring annotations work: Annotation scanning: When the Spring Framework starts up, it scans the classpath for classes that are annotated wi...

gRPC and Spring Boot: A Match Made in Heaven

-
Image
  What is gRPC: gRPC is a modern, high-performance, and lightweight open source framework for building scalable, distributed systems. It is a highly efficient and low-latency framework, designed to work over a variety of transport layers, such as TCP, HTTP/2, or even unencrypted UDP. gRPC supports multiple programming languages, such as C++, Java, Python, Go, and Ruby, so it can be used to build a wide range of applications and services. To know more about gRPC and REST API comparison here is  my blog link: What is Spring Boot: Spring Boot is a popular open source framework for building web applications and microservices using the Spring framework. Some key features and benefits of Spring Boot: Auto-configuration, Embedded Servers, Standalone application, Ease of integration with other OSS projects like spring cloud, Spring data, Apache camel, Kafka etc. Here is an example of a gRPC service implemented using Spring Boot: Step 1: Start by adding the gRPC and Spring Boot depende...

gRPC or REST: Choosing the Right API Design for Your Needs

-
Image
  There are several advantages of gRPC over REST APIs: Performance: gRPC uses a binary format for data serialization, which is more efficient than the text-based format used by REST. This makes gRPC faster and more suitable for use in high-performance environments. Bi-directional streaming: gRPC allows for bi-directional streaming of data, which means that both the client and the server can send streams of data to each other. This is not possible with REST, which is only able to send data in one direction (from the client to the server). Interoperability: gRPC supports multiple programming languages, so it is easier to create cross-language APIs. REST APIs are limited to the capabilities of the HTTP protocol, which may not be sufficient for certain use cases. Simplicity: gRPC uses a simple HTTP/2 protocol and provides code-generated stubs to make it easier for clients to use the API. In contrast, REST APIs require clients to construct URLs and understand the format of the URLs in o...

API Benchmarking with Gatling

-
Image
  What and Why Performance Measurement: The downtime of a mission-critical application can be very costly in recent time. It can lead to customer loss or financial loss. In today's world most of the web applications are built using APIs.  APIs should be functionally correct, as well as available, fast, secure and reliable. It is very important to gather the data about API performance periodically. This will give us information about health and hygiene of our application.  It doesn’t matter how beautiful your front end applications are if the API data sources take several seconds to respond or even worse if API performance is not consistent. API Performance matters very much in a world of microservices, which means the source of what a client application shows is probably being aggregated from multiple APIs behind the scenes. How to Measure API Performance: There are many tools available for performance measurement. This page list open source tools for performance measurem...
