These new, boosted processes include much better flexibility, reduced costs, greater effectiveness, enhanced safety, managerial ease, and reduced investments in infrastructure.
Reliability, nonetheless, will be the topmost concern amongst IT executives when referring to this new model set by cloud computing systems. Usually, 3.65 times down-time in a year is typical for non-redundant hardware which includes reload time of the OS and backup restorations.
For the organisation, downtime can be classified as planned or unplanned. When it comes to cloud computing, it has the advantage of planned downtimes over other technologies. Nonetheless the biggest advantage of deploying cloud computing is minimum unexpected downtimes. The planned downtimes are scheduled for software upkeep, upgrades, or hardware repairs.
Scheduled downtimes are kept to a minimum in cloud computing because this is what they are selling (higher uptime). Providers have the experience and proven processes that can provide the general network trustworthiness and which could easily surpass the services provided by common data centres, or solo servers.
Service level agreements (SLA)
In spite of the many claims of trustworthiness, most cloud vendors do not offer fixed SLAs which would assure controlled downtime, or offer reimbursements to firms to cover their losses for extended downtimes.
Cloud backup providers with applications that have self-healing capabilities ( or some similar technologies ) can suffer from unplanned downtimes due to many factors, but mainly due to human error.
In order to guarantee reliability, a robust backup plan is vital. However, in cloud systems designed with the latest and highly dependable software technologies, managers usually tend to forego such obligatory backup strategies. Without a backup strategy, systems can collapse at any time, and this applies to both cloud and non-cloud systems. Data loss is also a strong possibility. The sole saving-grace that cloud backup systems have over other systems, is the inexpensive and huge storage facility for the storage of data backups.
Security measures provided by cloud backup providers may vary from one vendor to another. However, much of today’s backup software is reserved for physical servers, and not for the virtual environments within a cloud computing company. The outcome is that these solutions might entail high costs. Many of today’s backup applications generally charge on a per server basis.
Unplanned downtimes could be catastrophic to your system along with the information that you have stored. A remote monitoring strategy can scan your servers for faults, impending application issues, or just to enhance the present general performance levels. It may alert you to approaching downtime, or conditions that can trigger downtimes.
