High Availability backup services for business
There are many options now available in the space of backup services for business. One of the more popular options today is that of a High Availability configuration. We’ll investigate what High Availability is; and how it’s a legitimate backup service for business.
What is High Availability?
High Availability is a characteristic of an overall system or environment. The basics premise is that a system or service is always usable or accessible when a user requires it. If the system or service is down; then it’s deemed to be unavailable.
There are three key principles that are taken into account when it comes to making sure an environment passes the High Availability test.
No single points of failure.
Put another way; there needs to be redundancy. If there is a single point of failure and it does fail; then the entire system becomes unavailable.
Reliable failover or crossover.
A common mistake that’s made is the failover mechanisms create a single failure point. This means that the environment needs to have multiple failover and crossover points installed so that if one fails; another route will be taken.
Failure and error detection and management.
The whole point of High Availability is that an end user may never see an error. However; monitoring and management of the environment means that all errors need to be picked up and dealt with promptly.
Benefits of High Availability
Protection from Downtime
In today’s world; access is king. Businesses rely on their data and systems being accessible to function day to day. Should a key business system or service become unavailable; it has the ability to cripple a business until the incident is resolved.
In a High Availability environment; it simplifies the process to migrate the service to a new host and continue running. Even though the system maintenance guys will be working hard at restoring the original system as quickly as possible.
Reduces lost productivity and revenue
Depending on where you look; the cost per hour of downtime for a business can be anywhere between $8000 to $74,000. Regardless of the finer points – businesses won’t survive downtime if it’s a regular thing.
You’ll also lose productivity from your team as they’re unable to perform their tasks and brand damage cause by IT outages could cost current and future deals.
While unexpected downtime is really disruptive; scheduled downtime can also be just as costly for businesses. Changing out hardware; applying system and software updates are sometimes re-scheduled due to the downtime they can create.
In a High Availability environment; maintenance downtime can be reduced heavily and take the deterring factor of deferring important upgrades and updates away – all while no one outside of IT even knows something is going on.
Improves resilience in your environment
While Disaster Recovery environments can take time to co-ordinate; High Availability can allow for a failover time (or Recovery Time Objective) of seconds. Data replication is highly configurable; with the ability to sync data across to the HA site pretty much immediately if needed.
This means that if a failover is to occur; then the data is up to date and end users wouldn’t even know if a change has occurred or not. This makes for a seamless transition.
