What is Load Balancing?
Hey friends,
Load balancing is fundamental to achieving scalability and high availability in the cloud. It’s also a concept that gets asked in cloud interviews, but what is it?
Load balancing distributes incoming network traffic across multiple servers, known as backend servers. This distribution aims to ensure that no single server bears too much demand, which helps to keep the application running smoothly by reducing individual server load and, by extension, preventing overloading that can lead to server failure.
How Load Balancing Works
Incoming User Requests: The diagram shows three users, each using a device to send requests to a service.
Load Balancer Role: The load balancer acts as the traffic cop in front of the servers. It receives incoming requests and then distributes them across multiple backend servers.
Distribution Mechanism: The load balancer uses algorithms to decide which server to send each request to, keep traffic evenly distributed, and optimize the use of server resources.
Importance of Load Balancing
Reduces Downtime: The risk of any server failing decreases by spreading the load across several servers. If one server goes down, the load balancer redirects traffic to the remaining operational servers.
Enhances Performance: Load balancing helps to prevent any server from becoming a bottleneck, thereby improving the responsiveness and availability of applications.
Scalability: As an application's user base grows, load balancers make it easier to scale resources up or down. New servers can be added to the pool without disrupting the service, and traffic can be managed according to the current demand.
Cloud Engineer Academy Launch
Tomorrow, February 4th, the Cloud Engineer Academy will be launched. I’m so excited for the students to start learning and seeing what’s inside.
I thought I’d answer a few questions before tomorrow as the price is increasing.
What is the Cloud Engineer Academy?
The academy is a 12-week hands-on course where you will learn everything about cloud engineering from the ground up. It’s self-paced so that you can learn it in your own time.
Who is it for?
The academy is for anyone who wants to learn more about cloud technology and gain practical hands-on skills, regardless of their technical expertise.
Our current students include Beginners, Software Developers, DevOps Engineers, Network Engineers, and QA/System Testers.
