Unveiling CloudFront: Empowering DevOps Freshers to Supercharge Content Delivery

-
Image
Let’s start off by looking at what a CDN is and why we use one? CDN stands for Content Delivery Network. It is a very large distribution of caching servers that are located around the world. It contains content that are stored in your origin servers and routes the viewers to the best location so that they can view the content that is stored in the cache. The content can be static (content that does not change)or dynamic (content that does change) in nature. CDN adds to the scalability and performance factor of applications. CloudFront is Amazon’s global content delivery network with massive capacity and scale. It is optimised for performance and scalability. Security features are also built in and you can configure them for optimal service. The user is in control of the service and can make changes on the fly. It includes real time reporting so that you can monitor the performance and make changes to the application or the way the CDN interfaces with your application. It has been optim

Introduction : LEGO blocks have always been a popular toy, allowing us to unleash our creativity and build various structures. Similarly, in the world of computers, there's a tool called Docker that shares some similarities with LEGO blocks. Let's explore this connection! In our daily lives, we encounter numerous applications on our devices, ranging from games to educational tools. Have you ever wondered how these applications are developed? Software developers use different tools and languages to construct them, just like building with LEGO blocks. However, a challenge arises when these applications are moved from one place to another, such as from a developer's computer to a cloud server. Sometimes, essential elements are missing or incompatible, causing the applications to malfunction. It's like trying to fit your LEGO creation into different rooms with varying settings – some rooms may not have enough space or the right setup. This is where Docker comes to the rescu

Hello Everyone, Today lets see how to encrypt and decrypt the data using pgcrypto extension. Encryption and decryption are important aspects of database security. In this blog post, we will explore how to encrypt and decrypt data in PostgreSQL using command-line tools. First, let's discuss the basics of encryption and decryption. Encryption is the process of converting plaintext data into a ciphertext format that can only be read by authorized users. Decryption is the reverse process of converting ciphertext data back into its original plaintext format. PostgreSQL supports several encryption and decryption functions that can be used to secure your data. One of the most popular encryption methods in PostgreSQL is the pgcrypto extension, which provides several cryptographic functions that can be used to encrypt and decrypt data. Now lets see how to encrypt and  decrypt the data at column level using pgcrypto extension. 1. First lets create a sample database named eminds using command
