High Availability (HA) - Always available!

High availability is essential for critical applications. Failures are associated with high costs and often also with a loss of trust and reputation. We help you with the right infrastructure to prevent this from happening in the first place!

What does High Availability (HA) mean and why is it so important for (some) companies?

High Availability (HA) refers to measures and architectures that ensure that an IT system or service is continuously available and has minimal downtime.

This is crucial for critical applications where interruptions can have costly and serious consequences.

In the context of infrastructure and hosting, HA comprises several core components. By combining these strategies, organizations can maximize the availability of their systems and ensure that they remain operational even in the event of disruptions.

High Availability (HA) core components

Redundancy
  • Server redundancy: Provision of multiple physical or virtual servers to ensure that the failure of one server does not cause an interruption of service.
  • Database redundancy: Use of replication and clustering to ensure that data is available on multiple database instances.
Load balancing

Distribution of data traffic across several servers to prevent overloading and increase availability. Load balancers can be both hardware and software-based.

Failover mechanisms

Automatic switchover to a standby server or another component if a primary system fails. This includes failover of both servers and networks.

Georedundancy

Placement of infrastructure components in different geographical regions to protect against regional failures such as natural disasters or local power outages.

Automation and orchestration

Use of tools and scripts to automatically monitor and restore services. Orchestration tools such as Kubernetes help to distribute containerized applications to different nodes and start them automatically in the event of failures

Regular backups and disaster recovery (DR) plans

Regular backup of data and system states and plans for rapid recovery in the event of a catastrophic failure. DR plans must be tested and updated regularly

Network redundancy

Use of multiple network connections and ISPs to ensure that a connection failure does not lead to a service outage

Monitoring and alerting

Implementation of monitoring solutions to continuously monitor system statuses and detect problems at an early stage. These systems should trigger alarms and, ideally, initiate automatic corrective measures.

What we offer!

It is important for us to understand your current infrastructure and the need for a highly available solution for you. The cost-benefit analysis is the top priority for many of our customers.

Many companies do not realize that, depending on the type of protection, the costs often exceed the benefits. A joint analysis with us with the corresponding options for implementation is part of our consultation. Only then do we implement and, if necessary, operate your individual solution.
