Cloud designs are utilized extensively these days; the cloud is a plenty of astounding choices regarding administrations and arrangements. Nonetheless, with awesome power comes incredible duty, and the cloud presents itself as a place where disappointment can and in the long run will happen. Along these lines, thusly, it will spread upon the whole engineering quick, conceivably causing enormous blackouts that can leave a business on its knees.
Affirm, that is not an excessively hopeful situation – more probable the inverse – however not to fear. This is the idea of any engineering – and for what reason should cloud be any unique?
Cloud planners confront two unique issues at scale at any given time so as to get ready for the most exceedingly awful; right off the bat, if something surprising and undesired happens, how to proceed with business tasks as though nothing happened, and furthermore, if something sudden and undesired happens and I can’t proceed with activities of course, how might I bring the design up somewhere else and inside a sensible window of time, and afterward, continue activities not surprisingly?
In these terms we can discuss:
– Continue business as usual in the face of an outage
– Resume business as usual in the shortest term possible in the face of an irrecuperable outage
The first is covered by high availability, and the second is covered by disaster recovery. Here, we will look at high availability.
