E-GuideHow to identify which applicationsare right for public cloudcomputingThe benefits of server virtualization are proven by now, but the fact is,many small and medium-sized businesses (SMBs) haven’t been able torealize the benefits due to cost restraints. But the emergence of publiccloud computing has helped SMBs take advantage of virtualization’sefficiencies. In this e-guide from SearchCloudComputing.com, gainexpert insight into how public cloud computing benefits businesses ofall sizes. Discover how to identify which applications are goodcandidates for cloud computing and which are not.

SearchCloudComputing.com E-GuideHow to identify which applications are right for public cloud computingSponsored By: Page 3 of 8Public cloud computing levels the playing fieldBy Mark VaughnNew technology terms and marketing lingo are always popping up, and the cloud computingmarket is one of the biggest offenders.The onslaught of such terms as IT as a Service, Infrastructure as a Service, Platform as aService and Software as a Service has led to a rush on buzzword bingo cards. As much as Ihate to add to the chaos, I am proposing my own new term: Cloud as an Equalizer. CaaE,as I like to call it, is not a technology, but rather a statement about technology.Leveling the playing fieldWe always talk about the proven benefits of server virtualization, but the fact is, many smalland medium-sized businesses (SMBs) havent been able to realize these benefits because ofcost restraints, the complexity of the technology or a lack of staff to support the virtualinfrastructure.The emergence of cloud computing (particularly public cloud) has helped SMBs takeadvantage of virtualizations efficiencies. And these efficiencies have created newopportunities previously afforded to only the largest and most complex organizations --hence, Cloud as an Equalizer.One of the equalizing features of public cloud computing is agility. Cloud computing allowsmore organizations to respond to real-time market conditions and bring services to marketin record time. This agility can allow even the smallest of companies to be the catalyst for atipping point in their markets, putting them in the right place at the right time.A word of caution, however: Being in the right place at the right time is good only if you cantake advantage of the opportunity. Growing too fast can be even more damaging thangrowing too slow. If you hit the right niche at the right time, you can quickly outgrow yourcapacity to deliver and destroy your business before it ever gets off the ground.

The ability toquickly scale your services to meet fluctuations in demand can help you ride the wave ofbeing first to market, then allow you to scale back and control costs as that initial demandslevels out.In the old days of virtualization, before public cloud computing, agility was an expensiveluxury that few could afford, and elasticity simply did not exist. If you wanted to handle ahigh volume, you signed a three-year commitment to that capacity. Matching capacity todemand was a difficult balancing act. It led to the downfall of many SMBs and gave anadvantage to larger shops that could more easily adjust to changing capacity requirements.Now public cloud computing has presented SMBs with the chance to level the playing fieldand compete in the major leagues. SMBs can use the cloud to respond quickly, grow ondemand and shed resources when they are no longer needed.Enterprises had better take notice. Tomorrows competition may just as easily come fromthe startup on Main Street as from the corporate competitors they are accustomed tobattling.

They are also largely in agreementthat not every application or every enterprise would be a fit for private cloud computing.Cloud computing is all about efficient use of resources, principally, managing capital andtechnology support costs. Finding where resource efficiency could be low is the key tofinding cloud computing applications.Good candidates for the cloud:• Applications that are used by a group of mobile workers to manage their time andactivity, and that contribute only limited information to the companys broadmanagement information databases. Sales support and field service supportapplications are good examples of this.• Applications that require system hardware or software not normally used by yourcompanys IT operations. An example would be a Linux application in a Windowsshop.• Applications that are run infrequently but require significant computing resourceswhen run. The cost of sustaining the excess internal IT capacity for theseapplications can be significant. This is particularly true if the applications must be runad hoc, and thus could collide with normal IT schedules.• Applications that are run in a time zone different from that where your companys ITpersonnel are located, depending on how much usage is offset with your supportstaff. Here, cloud-sourcing may be a better alternative than starting your own multi-shift support operations.

The cloud is agood framework for testing and prototyping application changes, even if the finalapplications will be run on your own infrastructure.• If your company is planning on outsourcing web hosting and Internet-hostedcustomer or employee services, the back-end server portion of these applications aregood candidates for public cloud computing implementation.• Companies who have distributed server locations and data centers to support a setof applications used throughout the company. By creating a larger resource pool, youmay be able to make more efficient use of servers and storage, lowering equipmentcosts, and also support your IT investment more efficiently. The more servercomplexes your company uses, the more it stands to gain from private cloudcomputing.• Companies who want to have backup for critical applications are good candidates forboth public and private cloud computing. By creating a cloud-friendly internal ITstructure, youll find it easier and more efficient to outsource applications to thecloud if internal systems fail or are overloaded.Obviously, the more of the above factors apply to a given application, the more likely it isthat the application is a candidate for the cloud. There are other factors that can make cloudcomputing use more problematic, though.Bad candidates for the cloud:• Applications that involve extremely sensitive data, particularly where there is aregulatory or legal risk involved in any disclosure, will require special treatment ifthey are to be run on a public cloud. It is smart to get a legal opinion beforecommitting any applications of this type to public cloud computing.• Applications now being run on the companys private network and that are veryperformance-sensitive may create user experience issues if theyre run on a publiccloud. It is normally more difficult to control network performance for public cloudservices.

Loading the database onto the cloud may be costly and also create dataharmonization problems with internal uses of the data, and accessing the data fromthe cloud is very likely to create performance problems.Even where cloud computing is a viable choice, there may be better ones available. In manycases, it will be possible to use software-as-a-service (SaaS) instead of public cloudcomputing services. Sales and support applications (CRM, in particular) are popular in SaaSform, and SaaS eliminates application management and support costs that are almostalways a part of even public cloud computing services. Personal productivity tools like"office suites" can also be obtained online from many sources, and even unifiedcommunications and collaboration tools are available as hosted services.Experienced enterprise planners know that cloud computing, like most trends and newconcepts in the industry, has tended to be over-publicized. That can create unrealisticexpectations and disappointing results from early implementations. The best way to preventthis is to have a realistic plan for cloud computing adoption, one that assures theapplications being targeted are the ones with the best potential for generating benefits.
