Whereas the pattern towards cloud infrastructure and hyperscale knowledge facilities means enterprises are rising extra depending on third events for his or her IT operations, a current Uptime Institute survey discovered that 48% of North American organizations nonetheless depend on on-premises knowledge facilities.
For these organizations, it’s essential that they spend money on and preserve excessive availability to make sure mission-critical methods and companies run as anticipated.
As a enterprise crucial, excessive availability is significant to sustaining enterprise continuity, maximizing buyer satisfaction, and minimizing monetary losses. Whether or not you’re ranging from scratch or are liable for present methods and demanding infrastructure, three key steps should be mastered to attain excessive availability:
-
Safety of the bodily plant
-
Architecting a resilient infrastructure
-
Choosing the proper operational instruments
Bodily Knowledge Middle Safety
Addressing vulnerabilities within the facility housing a company’s knowledge middle is usually an ignored facet of excessive availability.
Whether or not that knowledge middle is a standalone construction or devoted house inside a bigger campus, investments in resilient IT structure, glorious operational instruments, and a meticulous response technique are moot in case your IT infrastructure is topic to points like malicious human intrusion, environmental failures, energy outages, or different disasters.
To protect towards and decrease the chance of avoidable non-cyber incidents like these requires bodily safety measures, together with:
-
Safety cameras for real-time monitoring
-
Sturdy entry controls to restrict entry to approved people
-
Dependable energy infrastructure, together with a generator and an uninterruptible energy provide (UPS)
-
Fuel-based fireplace suppression methods, akin to FM-200
-
Environmental monitoring with temperature and humidity controls
Resilient IT Structure
A cornerstone of excessive availability is the redundancy of IT infrastructure. By figuring out potential essential single factors of failure and, the place attainable, making certain there may be an choice for failover to a secondary useful resource, you may cut back the chance of downtime within the occasion of an incident. Redundancy ought to lengthen throughout each {hardware} and software program layers.
Implementing failover clusters, resilient networking paths, storage redundancy utilizing RAID, and offsite knowledge replication for catastrophe restoration are confirmed methods. Adopting a hybrid or multi-cloud strategy may cut back reliance on any single service supplier.
Should you function an off-site knowledge middle, guarantee it’s not depending on the identical energy supply as your fundamental campus. You’ll want to have a catastrophe restoration and enterprise continuity plan that features native and offsite backup storage.
Excessive Availability Operational Instruments
You’ve protected your knowledge middle and constructed a resilient IT infrastructure. Now it’s time to make sure all the things works the way you want it to. Meaning selecting instruments that allow you to reply to incidents and execute response plans as meant, embrace automation the place attainable, and make good selections below strain when issues have gone incorrect.
As a result of good selections require good knowledge, step one is investing in IT operations administration instruments that excel at discovering community belongings, ingesting their knowledge, and updating a configuration administration database (CMDB).
Constructing from a basis of correct knowledge, software efficiency monitoring (APM) instruments are a sensible choice for gaining a exact understanding of the well being of the methods comprising the community. APM and community monitoring platforms give IT administration the knowledge to make well timed selections for operational points like upkeep, load balancing, and incident response. That’s necessary for sustaining excessive availability (HA) since dangerous selections improve the chance of service outages ensuing from preventable system failure.
Whether or not your infrastructure is on-premises, cloud-based, or hybrid, the opposite key element to attaining excessive availability is the institution of failover clusters to facilitate – and even automate – the motion of companies and workloads to a secondary useful resource. Whether or not {hardware} (SAN-based) or software program (SANless), clusters assist the seamless failover of companies to again up sources and guarantee continuity within the occasion of a severely degraded efficiency or an outage incident.
Enterprises right now are likely to favor excessive availability SANless clusters for his or her flexibility working in IT environments extra closely depending on cloud methods and companies, digital machines, and software program. SANless clusters provide the identical performance as legacy SAN clusters however with extra flexibility and decrease value. Furthermore, SANless clusters assist on-premises, cloud, or hybrid infrastructure and may assist geographically distributed knowledge facilities, which is a key consideration in community resiliency and catastrophe planning.
Preserving Providers On-line
With tendencies like hyperscale knowledge facilities, cloud workload repatriation, and digital transformation in full bloom, a lot is altering for right now’s IT operations managers.
Nonetheless, one constant requirement is conserving companies obtainable to customers and avoiding downtime. With planning that features bodily safety, resilient structure, and excessive availability, you may maintain your customers and prospects completely satisfied.
