Best CI/CD Practices for Better Code Quality
Best CI/CD Practices for Better Code Quality
Continuous integration and continuous delivery, also referred to as CI/CD, are a tradition, set of basic concepts, and set of practices that application development teams use to deliver code changes more frequently and reliably. Continuous integration is a coding philosophy and set of techniques that encourage development teams to commit tiny code changes to a version control repository regularly. Because most current applications include writing code on a range of platforms and tools, teams want a standardized method for integrating and validating changes. Continuous integration allows developers to build, package, and test their applications in an automated manner. Developers are more likely to commit code changes more frequently when they have a consistent integration procedure, which leads to improved cooperation and code quality. Continuous delivery is a software development approach that automates the infrastructure provisioning and application deployment process by combining it with continuous integration. After code has been tested and built as part of the continuous integration process, continuous delivery takes over in the last stages to ensure it can be deployed to any environment at any time. Everything from infrastructure provisioning to application deployment to the testing or production environment can be covered by continuous delivery. The program is constructed in such a way that it may be deployed to production at any moment with continuous delivery. Then you may either manually trigger the deployments or switch to continuous deployment, where the deployments are also automated.

Load Testing Tips
Load Testing Tips

A load test is a technique used to measure the response of a system under various load conditions. It assists in identifying the maximum capacity of an application and also any bottlenecks and finds out which element is degrading.

Load testing is a crucial component of performance testing that is gaining immense importance in today’s digital-driven world. Performance testing gauges whether a web application can handle high volumes and patterns of traffic before it goes live. It is a practice in which the performance of the system is tested under peak traffic conditions for web applications and APIs. By simulating the concurrent access of multiple users to an application, testers create a model of the expected usage of the application.

Building Resilient Applications – Popular Design Principles & Using NetHavoc to Test Efficacy

Introduction

For microservices, it’s crucial to conduct resiliency testing to ensure that the system can recover from failures and keep operating as expected. Gartner reports that on average, IT downtime costs $5,600 per minute, with the cost of an hour’s downtime ranging from $140,000 to $540,000 depending on the business. A survey shows that 98% of organizations estimate the cost of a single hour of downtime to be over $100,000, while 81% say it costs over $300,000. Any disruption or downtime in these systems can lead to significant financial losses, damage to the organization’s reputation, and loss of customer trust. This is where Cavisson, a leading enabler for Fortune 100 organizations in their quest towards digital excellence, comes in. One of the key ways in which we help businesses reduce their IT downtime costs is via our chaos engineering tool, NetHavoc. This blog will explore some of the most popular design principles for ensuring resilient microservices based applications and how you can leverage NetHavoc to test their effectiveness.

What is resiliency testing?

System downtime is no longer an option. If a user is unable to access an application once, they are unlikely to use it again. Resilience is the system’s ability to gracefully handle and recover from such failures while still providing an acceptable level of service to the business. In a nutshell, it assesses the system’s resilience, introduces a flaw, and ensures that the system fully recovers. 

What are microservices?

Software architecture style that involves breaking down a large application into a set of smaller, independent services that can be developed, deployed, and maintained separately. Each service typically has a well-defined interface and communicates with other services via lightweight protocols such as HTTP or messaging systems like RabbitMQ or Kafka. Microservices are designed to be highly modular, scalable, and resilient, and are often used in large, complex systems that require a high degree of agility and flexibility. By breaking down an application into smaller, more manageable components, microservices allow developers to make changes and updates to specific parts of the application without affecting the entire system, leading to faster development cycles, better fault tolerance, and easier maintenance.

HTTP/3 – Getting ready for the future with Cavisson NetStorm
HTTP/3 - Getting ready for the future with Cavisson NetStorm

HTTP/3 is the upcoming version of the Hypertext Transfer Protocol (HTTP), which is the underlying protocol used for communication on the World Wide Web. Let us look at some of the most significant changes being made in HTTP/3 and how it proves to be beneficial for both organizations and end-users alike:

QUIC –  Secure and reliable connection in a single handshake

QUIC enables secure and reliable connections in a single handshake. This is achieved through a feature called “0-RTT” (Zero Round Trip Time), which allows the client to send data to the server in the first packet itself, without waiting for a response from the server. This reduces the latency and speeds up the connection establishment process. QUIC is that it runs over UDP, which is a connectionless protocol that is less prone to congestion and provides better performance in high-latency networks. QUIC also includes built-in congestion control mechanisms that are designed to prevent network congestion and ensure fair sharing of network resources among different connections.

Common Application Performance Bottlenecks—And How to Avoid Them?
Common Application Performance Bottlenecks—And How to Avoid Them?

In computing, the term “bottleneck” refers to an overloaded network, a device whose one component is unable to keep pace with the rest of the system, thus slowing overall performance, or an application issue that may be causing your customers/end-users to wait indefinitely while performing business critical operations. 

Fixing bottleneck issues usually results in returning the system to a stable level of performance; however, to fix bottleneck issues, it is necessary to first identify where the issue lies which decides the all-important metric(s) – mean time to detect (MTTD) & mean time to resolve (MTTR). 

Poor application performance can be caused by a variety of factors. Even just a few seconds of application downtime can have an adverse effect on revenues, reputation, and customer satisfaction. Understanding and overcoming barriers to optimal application performance is crucial to delivering the best experience to each user.

Best Practices for API Testing
Best Practices for API Testing

Introduction​

APIs are the “middle man” between the layers and systems in an application or software.  API (application programming interface) testing occurs at the message layer without GUI. During integration testing, it is determined whether the APIs meet the testers’ expectations regarding functionality, reliability, performance, and security. When faults occur, they are costly, both in terms of the direct costs of resolving the defects and in terms of the indirect costs of damaged relationships, lost business, and missed development time. Inadequate software testing raises the risk of developer issues, stakeholder displeasure, and poor customer experiences. API tests are the quickest ways to check the functionality, reliability, performance, and security of the programming interfaces. An API is a software middleman that allows two programs to communicate with each other or the “middleman” of the layers and systems of an application or software. An application programming interface (API) is the interface that allows various software to communicate with one another.
