An In-Depth Look into Deployment Strategies: Pros, Cons, and the Role of Load Balancers and API Gateways Software deployment is an intricate process involving all the activities that make a software system available. Several deployment strategies have evolved, each with unique characteristics, benefits, and drawbacks. This article deep into five techniques: Big Bang Deployment, Blue-Green Deployment, Canary Deployment, Feature Toggle Deployment, and A/B Testing Deployment. We’ll also discuss the importance of load balancers and API gateways in these strategies....
What is API Gateway?
An API Gateway is a server that acts as a ‘gate’ between applications and microservices, facilitating communication between them. It is the main entry point for data flowing into your applications from various sources, and it helps streamline and manage these data interactions. The concept of an API Gateway is particularly significant in microservices architecture, where it helps manage and route requests to the right services. How does it work? An API Gateway works as a reverse proxy that accepts API calls, routes them to the appropriate microservices, and then consolidates the results to respond to the client....
What is DNS?
A Comprehensive Look at the Domain Name System (DNS) What is DNS? DNS, short for Domain Name System, is the protocol within the set of standards for how computers exchange data on the internet and many private networks, known as the TCP/IP protocol suite. Its fundamental job is to translate human-friendly hostnames, like “www.example.com”, into machine-friendly IP addresses, like “192.0.2.1” (IPv4), or more complex versions like “2001:0db8:85a3:0000:0000:8a2e:0370:7334” (IPv6). This system allows us to use an easy-to-remember website name rather than the numerical IP address that computers use to identify each other on the network....
HTTP/2 vs HTTP/1.1
What is HTTP? HTTP, short for Hypertext Transfer Protocol, is the foundation of any data exchange on the Web, and it is a protocol used for transmitting hypertext requests and information between servers and browsers. It’s a client-server protocol, meaning requests are initiated by the recipient, usually the web browser. A complete document is reconstructed from the different sub-documents fetched. What is HTTP/1.1? HTTP/1.1 is the version of HTTP that has powered the Web for many years....
What is HTTPS?
Understanding HTTPS: Importance, Mechanism, and Benefits The internet is a vast network of data transferred from one point to another in a complex system of requests and responses. One crucial element in this network is the HyperText Transfer Protocol Secure (HTTPS), the security backbone of online communication. This article will explore HTTPS’s essence, workings, and significance and how it differentiates from HTTP. We’ll also touch upon the consequences of not using HTTPS and how a website can implement HTTPS using nginx or haproxy....
