High Availability

Welcome to SpamCloud's High Availability Solutions

High Availability (HA) is the ultimate safeguard for businesses in Chennai and beyond, ensuring seamless and continuous system performance. SpamCloud's HA solutions have been trusted by numerous companies to keep their operations running smoothly.

high availability clusters

Our high availability server Clusters, comprised of grouped servers functioning as a unified system, are the backbone of uninterrupted operations. These clusters, also known as failover clusters when they share storage across multiple networks, replicate workloads and functions, ensuring your applications or services keep running even if a server in the cluster encounters a hiccup.

The application or service hosted by the cluster can continue to run uninterrupted by another ha server or node in the case that one of the servers in the cluster fails. You may prevent their from being a single point of failure for critical processes and completely eliminate downtime by establishing high-availability clusters.

HA clusters are regularly tested to ensure that nodes are always ready. IT administrators often monitor cluster health using the free Heartbeat application. The script sends data packets to each machine in the cluster to make sure everything is working as it should.

IT business continuity versus high availability?

high availability cloud server IT systems and services are designed to remain usable 99.999% of the time, including during planned and unplanned outages. The so-called "five-nine reliability system" is almost constantly on.

If a critical piece of the IT infrastructure breaks but is still being kept up by a high-availability design, the backup system or component takes over. Users and programmes may access the same database that was available before the interruption, allowing them to go on with their job undisturbed.

When restoring essential IT services and components after a disaster, IT companies should follow certain procedures, utilise certain technologies, and adhere to certain rules. An illustration of a cyber disaster is when a large earthquake destroys a data centre.

High availability is a method for dealing with small but severe failures of easily replaceable IT infrastructure parts. To deal with significant events that might bring down the entire IT infrastructure, a process known as IT disaster recovery is implemented.

Outstanding Reliability in Load Balancing

Complete availability is frequently expressed using the percentage of availability. Excellent operational performance may be achieved by deploying a highly available load balancer on either a single node or a cluster.

In a single-node system, a single ha load balancer manages all administrative tasks and gathers and analyses all analytics. The load-balancing controller has node-level redundancy thanks to additional nodes in a high-availability load-balancing cluster, which also improves performance for CPU-intensive scans.

benefits of greater accessibility

planned interruptions

When you must take systems or data offline to perform critical maintenance operations, such as nightly backups or the installation of new hardware or software

unplanned interruptions

High availability systems can offer protection against unforeseen outages brought on by human mistake, programming errors, hardware problems, and environmental hazards.

Disaster recovery

In the case of an emergency, mission-critical software is restored and run at a distant site using a variety of tools, methodologies, services, and protocols.

load balancing

For load balancing, high availability systems can be employed. The most popular workload-balancing solutions include assigning tasks to the available resources.

The benefits of high availability

  • A reduction in downtime

  • SLA 1% or less

  • Confirmation of service continuity

  • Superb performance

  • Secure data

Why is a HA infrastructure necessary, exactly?

If you manage critical applications, operate high-traffic websites, and value uninterrupted service, a High Availability infrastructure is essential. At SpamCloud, we ensure your services are always reliable and accessible.

Components of infrastructure with high availability

High-availability IT infrastructure includes hardware redundancy, software and application redundancy, and data redundancy. In a high-availability cluster, redundancy describes the capacity of the high availability web server or high availability database components to perform the same tasks.

Data replication is the only way to achieve high availability. The nodes in a cluster must be identical in order to share and duplicate data. To ensure that any node can step in and deliver the best service possible in the event that the server or network device it is supporting fails, the nodes must exchange the same information and interact with one another.

In order to ensure high availability service and business continuity in the event that a data centre fails, data can also be copied between clusters.

When a task carried out by a primary component that has failed is moved to a backup component, a high-availability cluster fails over. The upkeep of an off-site failover infrastructure is an advised technique for high availability and disaster recovery.

Monitoring the status of crucial core systems in case they fail or become overloaded allows IT managers to immediately divert traffic to the failover system.

Fault Tolerance

High availability and catastrophe recovery are crucial for company continuity. Together, they help businesses achieve high levels of fault tolerance, or the capacity of a system to continue functioning properly even when some of its hardware or software components malfunction.


high availability technology has a lower downtime objective than fault tolerance, which strives for zero downtime. For a high-availability system that aims to achieve operational uptime of 99.999%, or five nines, an annual downtime of 4.61 minutes is expected.

Delivering high-quality performance is not a priority for fault tolerance, in contrast to high availability. IT infrastructure employs fault-tolerance architecture to avoid mission-critical applications going offline.

Fault tolerance is more expensive in terms of cost than high availability. Since fault tolerance may require backing up whole hardware, software, and power supply systems, it is more expensive than high availability to ensure uptime. Physical components do not need to be replicated in high-availability systems.


The majority of business continuity plans contain high availability, fault tolerance, and catastrophic recovery solutions. Regardless of the size of the business, these actions provide support when a significant IT failure happens and help maintain essential activities. Both fault tolerance and high availability benefit users in the case of an IT disaster, therefore they work well together.
