Man­ag­ing Work­load on a Pub­lic Cloud

With CIOs now be­gin­ning to trust mov­ing crit­i­cal busi­ness apps on the pub­lic cloud, man­ag­ing the work­loads as­sumes more sig­nif­i­cance. Choos­ing the right cloud man­ager goes a long way ay in ef­fec­tively man­ag­ing work­loads

Lately, en­ter­prises have stopped be­ing shy about shift­ing their mis­sion crit­i­cal apps and data into the pub­lic cloud. It’s no sur­prise that CIOs are be­ing miserly about what they put into an in­ter­nal data cen­ter, con­sid­er­ing the pric­ing ad­van­tages and on-de­mand ser­vices that cloud of­fers to­day. An IDC sur­vey states that by 2018, pub­lic IT cloud ser­vices will ac­count for over half of the world’s soft­ware, server and stor­age spend­ing growth. The re­search firm also pre­dicts that pub­lic IT cloud ser­vices spend­ing will reach more than $127 bil­lion in 2018. Of course, se­cu­rity is a sig­nif­i­cant con­cern on ev­ery­one’s mind. It is a less known fact that pub­lic cloud can be as se­cure as any other com­put­ing en­vi­ron­ment through the joint ef­forts of IT and ser­vice providers. With the right cloud man­ager, you can avail the mul­ti­ple ben­e­fits of pub­lic cloud with­out any is­sues.

Once you have shifted the work­load to a pub­lic cloud, the im­me­di­ate con­cern is how you’ll man­age work­load on it. Cloud in­fra­struc­ture re­quires a dif­fer­ent ap­proach to work­load man­age­ment. Whether you’re al­ready on your way or just start­ing out, con­sider the fol­low­ing fac­tors when you pick out your ideal cloud man­ager:

Sim­plify Com­plex­i­ties

While cloud gives the free­dom to choose and al­ter op­er­at­ing sys­tems, data­bases, ap­pli­ca­tion frame­works, this cus­tomiza­tion leads to new com­plex­i­ties that didn’t ex­ist in tra­di­tional en­vi­ron­ments.A good and ef­fi­cient cloud man­age­ment so­lu­tion should give you cus­tomiza­tion along with the right man­age­ment tools, source con­trol and con­fig­u­ra­tion man­age­ment. At the same time, it’s im­por­tant to see how your phys­i­cal re­sources on the cloud are al­lo­cated and utilised with aids like graphs and sta­tis­ti­cal in­for­ma­tion.

Role-Based Ac­cess Con­trol

Good vis­i­bil­ity also means hav­ing roles and priv­i­leges built into the pub­lic cloud en­vi­ron­ment. A good cloud man­ager can en­able you to al­lo­cate ac­cess, based on the team one be­longs to or the po­si­tion he/she holds. With such a fea­ture, you can tune the sys­tem to en­sure that the stor­age team gets ac­cess only to their rel­e­vant data and ap­pli­ca­tions - for in­stance, cloud-based stor­age com­po­nents -while the vir­tu­al­iza­tion team gets ac­cess only to the vir­tual ma­chine man­age­ment. This iso­la­tion of roles creates ef­fec­tive au­dit trails and greatly re­duces the risk of a team mem­ber mak­ing in­cor­rect changes to the sys­tem.

Flex­i­bil­ity and Choice

As a client, you must ex­pect in­creased ef­fi­ciency along with the free­dom to choose cloud ser­vices that work best for your or­ga­ni­za­tion. An ef­fi­cient cloud man­ager should en­able en­ter­prises to eas­ily de­ploy and sup­port a se­cure, re­li­able and scal­able cloud in­fra­struc­ture. The cloud man­age­ment plat­form should ideally pro­vide flex­i­bil­ity that lets you to de­ter­mine the ideal mix of tra­di­tional and pub­lic cloud work­loads with­out wor­ry­ing about grow­ing man­age­ment costs.

“Your cloud man­ager should have the abil­ity to au­to­mate your or­ga­ni­za­tion’s ap­pli­ca­tions run­ning in one or more sup­ported clouds, in­clud­ing pro­vi­sion­ing, scal­ing, back up and disas­ter re­cov­ery.”

Au­to­ma­tion

Your cloud man­ager should have the abil­ity to au­to­mate your or­ga­ni­za­tion’s ap­pli­ca­tions run­ning in one or more sup­ported clouds, in­clud­ing pro­vi­sion­ing, scal­ing, back up and disas­ter re­cov­ery. In case of pub­lic cloud, the process of man­ag­ing ap­pli­ca­tions of­ten in­volves deal­ing with repet­i­tive tasks, es­pe­cially in large en­vi­ron­ments. It is­de­signed to be ad­min­is­tered by a man­ager, rather than re­ly­ing on man­ual pro­cesses to pro­vi­sion each server or push code. A cloud man­age­ment plat­form should re­duce op­er­a­tional bur­den and en­able en­ter­prises to sup­port ever-grow­ing com­put­ing re­quire­ments by au­tomat­ing pro­cesses.

Agility and Scal­a­bil­ity

Change is the only con­stant in busi­ness, and only com­pa­nies that are ag­ile will sur­vive. En­sur­ing agility will al­low com­pa­nies to in­no­vate and change course as re­quired. An ideal cloud man­ager will de­liver a dy­namic and flex­i­ble cloud in­fra­struc­ture, which will let your IT depart­ment rapidly re­spond to chang­ing needs of the busi­ness and cap­i­tal­ize im­me­di­ately on mar­ket op­por­tu­ni­ties. A cloud man­ager must also en­able en­ter­prises to build for the fu­ture. Con­se­quently, IT de­part­ments are ex­pected to keep pace with evolv­ing re­quire­ments of the busi­ness.If a large pro­ject comes up and calls for larger servers or mul­ti­ple servers, the cloud man­ager should al­low the busi­ness to scale up for the pro­ject eas­ily and quickly.

Sup­port Ap­pli­ca­tion Life­cy­cle

Man­ag­ing ap­pli­ca­tions will in­volve a list of events such as up­dat­ing code, per­for­mance op­ti­miza­tion, patch­ing se­cu­rity vul­ner­a­bil­i­ties, back­ups, ca­pac­ity man­age­ment and failover. Your cloud man­ager will en­able you to man­age th­ese tasksand equip you with tools that­mon­i­tor, alert, auto-scale and help with con­fig­u­ra­tion man­age­ment as well as disas­ter re­cov­ery. With th­ese ca­pa­bil­i­ties, your or­ga­ni­za­tion will be ready to man­age ap­pli­ca­tions across a multi- cloud port­fo­lio and fully re­al­ize ben­e­fits like cost sav­ings and agility ben­e­fits of a pub­lic cloud.
