It’s not a surprise that the world of operating systems constantly moves at a fast clip. As a leading cloud server provider, LayerStack keeps close tabs on the latest trends and updates our comprehensive library of operating systems so you won’t be missing out.
Recently added to our OS selection is the Rocky Linux 8.4 that has reached General Availability for x8664 and aarch64. It is created by one of the founders of the CentOS project as CentOS’s successor.
Not a Rocky user? No problem, we have plenty more where that came from. From Ubuntu, Fedora and Debian to AlmaLinux and Windows, LayerStack has gone out of our way and maintains a comprehensive library where you can find multiple versions of operating systems of almost every description.
For those special snowflakes out there, if you need an environment outside our official image list, don’t feel left out – because you are not! LayerStack allows you to upload your customized VM images, meaning you can enjoy the flexibility of bringing your own operating system images on our servers to fit your specific needs.

From your apartment furniture, to your cell phone data, to your entire application workload, moving stuff to a new environment can make you sweat bullets, but it doesn’t have to be. Our tech experts at LayerStack will do the heavy lifting for you – all free of charge. On top of that, you can enjoy a slew of benefits from the cloud packages in which we take pride.
Why migrate to LayerStack clouds?
We let the quality of our cloud infrastructure speaks for itself. Snatching top spots in various benchmark evaluations, our cloud solutions excel in web performance, CPU power, stability, disk I/O performance, network performance and many other areas, beating some of the biggest names in the field for our unparalleled functioning.
Our intuitive LayerPanel allows you to control the smallest details in a single portal. Build, manage and monitor the environment and receive insightful, broken-down analytics so you can make the best and informed decisions that drive your business.
And we don’t stop there. LayerStack’s development team works tirelessly and rolls out new features to further improve your cloud journey with us. Global Private Networking, Load Balancers and API are just the start – the sky is only the limit, not our cloud.
There’s no better news than being able to keep everything the way they were after a transition. We promise an easy and professional migration with minimal disruptions, and that’s what we deliver.
Our templates let you import your original VM images to preserve the software and previous configurations in your customed environment. You can install multiple instances from the same image and keep everything you know and love, at the same time enjoying the new benefits that LayerStack’s remarkable features offer.
2. Fuss-free migration delivered by experts
If all you want is a simple migration, you can have it too – for free! Our experienced experts have executed migrations of all sizes, and they will put together a migration strategy best to your situation for a smooth, simplified and swift migration with minimum downtime. During which, all data will be encrypted and transmitted over a secure channel, as security has always been our priority.
An essential triage to internet traffic with practical security features, load balancers is the gatekeeper that directs web-based traffic to the best available servers for optimal application efficiency. This process involves different algorithms, all come with unique pluses. And in this post, you will read all about them so you can make the most of our balancers.
This is the most common algorithm where all available servers form a queue. When a new request comes in, the load balancers forward it to the first server in the queue. Upon the next request, the balancers distribute the traffic to the next server in the list.
The below diagram gives you a picture of how this works. Say we have an environment with three available servers, the first client’s request (1) received by the balancer is assigned to server 1. The next request (2) is then assigned to the next server in turn, namely server 2. When the balancer finishes routing the third request and reaches the bottom of the server list, it directs the next client (4) to the first on the list again, which is server 1. And the cycle continues.
It is the simplest and the easiest algorithm to be implemented where each server handles a similar amount of workload, making sure there is no overload or starvation of server resources.
The name says it all – the balancers monitor the current capacity of each available server, and assigns new requests to the one with the fewest active connections.
In the diagram below, servers 1 and 2 are serving a higher demand of requests. Therefore, when client 1 comes in, their request is directed to server 4 as it is currently idle. The next client (2) is assigned to server 4 as it is now one of the two servers (3 and 4) with the least connections. Now, with server 4 having two connections while server 3 having just one, the third incoming client request is routed to server 3 – the one with the least active connections.
This intelligent mechanism ensures all requests are handled in the most effective manner possible, and is more resilient to heavy traffic and demanding sessions.
In similar nature to least-connection, source-based algorithm pairs certain requests with the client’s IP address. Once you set up the rules in the LayerPanel, our load balancers will route the workloads accordingly.
For instance, the balancer recognizes the IP address that you have previously specified, and autonomously directs the requests from that specific client to a specific server – server 2 – in the diagram below. When the same client returns a few days later with a new request, the balancer recognizes its IP address and will distribute the request to the same server.
This algorithm provides you with the flexibility to group certain application-specific tasks together or slightly tailor the environment best to process specific requests. This allows your application to handle requests with desirable resources and reach desirable, more predictable results.
