What is Serverless Computing?

 What is Serverless Computing?

Serverless computing is a term for a type of cloud computing where the cloud provider manages all the servers used to run applications and services. This can include provisioning, managing, patching, and upgrading servers. It also includes monitoring server performance and handling capacity demands.

Serverless computing means you don't have to think about servers. Your application still runs on servers, but your cloud provider like Amazon takes care of all the server management for you. This way, you can focus on your application code instead of worrying about servers. Amazon offers cost-effective services that provide built-in availability and flexible scaling, so your application can grow as needed.

What is AWS Lambda?

AWS Lambda is a compute service that lets you run code without having to manage servers. You create a Lambda function, and Amazon executes it for you. You can use Lambda to handle events such as processing images uploaded to Amazon S3, responding to web requests using Amazon API Gateway, or scanning files in an AWS S3 bucket for malicious content.

You can also use Lambda to run batch processes or cron jobs. For example, you can use Lambda to archive old log files to Amazon S3 every day at midnight.

AWS Lambda integrates with other AWS services, so you can easily create applications that are scalable and highly available. You can also use Lambda with other services outside of AWS. For example, you can use Lambda to send push notifications to an iPhone app using the Apple Push Notification Service (APNS) or to send emails using Amazon Simple Email Service (SES).

other services outside AWS

  • Apple Push Notification Service (APNS)
  • Amazon Simple Email Service (SES)

In a serverless world, you don't need to think about or manage servers. You can simply write code and let AWS take care of the rest. With AWS Lambda, you can run code in response to events, such as uploading an image to Amazon S3 or processing

Understanding Cassandra's Core Principles for Developers

Cassandra can be used for ensuring scalability, high availability, and performance across multiple data centers. Cassandra is schema-less and based on eventual consistency. Advantages of Using Cassandra Scalability: Cassandra is highly scalable; it allows for seamless horizontal scaling. You can add more nodes to the cluster without downtime, and Cassandra will automatically redistribute the data. High Availability: It is designed to avoid single points of failure and provides continuous availability. Fault Tolerance: Cassandra provides excellent fault tolerance through replication across multiple nodes. Data is automatically replicated across multiple nodes (according to the replication factor specified). This means that even if one or more nodes fail, the data is still available from other nodes. Write Performance: Cassandra offers fast write operations.  Decentralized Architecture: There's no master node in Cassandra; all nodes can handle read and write operations, which helps i...
