High Availability Hosting

When uninterrupted service is essential.

What High Availability Hosting, Clustering, and Load Balancing Are and Why You Need Them

High Availability Hosting: This ensures that your website or application remains accessible and operational with minimal downtime by using redundant systems and failover strategies.
- Why You Need It: Guarantees continuous service availability and reliability, crucial for maintaining business operations and user satisfaction.
Clustering: Involves grouping multiple servers to work together as a single system, sharing the load and resources.
- Why You Need It: Provides improved performance, redundancy, and scalability, allowing for better handling of high traffic and reducing the risk of system failures.
Load Balancing: Distributes incoming traffic and workload across multiple servers to ensure no single server is overwhelmed.
- Why You Need It: Enhances performance and reliability by optimizing resource use, improving response times, and preventing server overloads.

Implementing these strategies ensures robust, scalable, and reliable hosting solutions, crucial for maintaining high performance and uptime in your IT infrastructure.

For critical applications, systems, or websites where downtime is not an option, we customize our hosting solutions to meet your specific needs.

You set the requirements, and we tailor the solution to fit. With extensive experience in ensuring zero downtime, we provide daily solutions such as active/passive clustering, active/active clustering, geo clustering (geographically dispersed clusters), load balancing, failover replication, and SSL Offloading/SSL Accelerator. Rent only what you need from us. For example, you can choose whether you want front-end servers to be virtual while back-end servers are physical. Specify the size of the disks in the SAN cabinet, whether it should be 10 GB iSCSI, 12 GB SAS, 16 GB Fiber Channel, or a combination of all three. We also offer solutions with SSDs for enhanced performance.

Clustering:

There are two primary types of failover clustering. The first technique involves active/passive clustering, where one node is active and the passive node takes over if the active node fails. The second technique is active/active clustering. We also offer “Geo Clustering,” where nodes in the cluster are located in geographically distinct locations.

Load Balancing:

Load balancing is used to distribute the load evenly across servers to ensure that no single server becomes overwhelmed. This approach optimizes the performance and availability of your applications by preventing any single point of failure.

SSL Offloading / SSL Accelerator:

If, for example, you have an online store protected by an SSL certificate and you want the same SSL URL to be distributed internally across multiple servers, we assist with the installation and configuration of SSL Offloading/SSL Accelerator. We offer both hardware-based and software-based solutions to enhance your SSL performance and security.

Benefits of High Availability Hosting, Clustering, and Load Balancing

High Availability Hosting: Ensures your website or application remains operational with minimal downtime through redundant systems and failover strategies.
- Benefit: Provides continuous access and high reliability, crucial for avoiding disruptions and maintaining user satisfaction.
Clustering: Involves grouping multiple servers to function as a single system, sharing the load and resources.
- Benefit: Enhances performance, redundancy, and scalability, allowing for better management of high traffic and reducing the risk of system failures.
Load Balancing: Distributes incoming traffic and workload across multiple servers to prevent any single server from becoming overwhelmed.
- Benefit: Optimizes resource use, improves response times, and prevents server overloads, enhancing both performance and reliability.
