Cloud Computing Myth Busters - Know the Cloud

  1. 1. MYTHfacts straight.Get your Cloud BUSTERS
  2. 2. MYTH MYTH:BUSTER “A cloud provider cannot guarantee security.”NO. 1DATASECURITY FACT: From a physical standpoint, public cloud datacenters are amongst the most secure premises on the planet. Yet, at the logical level, a cloud provider with every security certification still cant guarantee the integrity of specific servers, applications, and networks, if your applications are poorly written, set up and secured. Heres where the IT Pros remain squarely in control and critical to cloud success. All the security practices of a cloud provider are meaningless if a customer organizations security practices are weak.
  3. 3. MYTHBUSTERNO. 2DATACONTROL MYTH: FACT: “My organization will The essence of cloud services is flexibility. One application may call another on a different cloud service, and data may be stored anywhere, be locked into one including your own network, but still be accessible to cloud applications. vendor and lose No cloud provider offers a service that completely takes control of your control of its data, if it environment. The best cloud solutions will be a combination of on and moves to the cloud.” off-premise services.
  4. 4. MYTH MYTH:BUSTER “My company must move all its applications to a cloudNO. 3 service to be able to benefit fully from cloud computing.”COSTSAVINGS FACT: Moving an entire datacenter to the cloud is nearly impossible. Nor is it recommended by any cloud provider. Start by identifying applications in your pipeline that can benefit your organization by being in the cloud. Look for applications where resources are used intensely for a short period each month then left idle for the rest of the time, or applications where a moderate level of resources are used continuously, but experience periods of very high activity. These applications are good cloud candidates, because the cloud can scale up and down resources on demand. The cloud is built for flexible access to resources that can be allocated to other applications, or even other customers, when idle.
  5. 5. MYTHBUSTERNO. 4PRIVATE PRIVATECLOUD MYTH: FACT: My company can Your company can benefit from a private cloud. The points to remember when talking to business management about a private cloud is that you still own get all the everything: hardware, software and, even uptime management accountability. This benefits of cloud means you have to manage the infrastructure and the capacity requirements to meet internal SLAs just as you do today. An on-premise private cloud is still a computing with CapEx expense, in contrast to cloud assets operated by a provider like Microsoft. a ‘private’ cloud running on our To realize the benefits of a private cloud, the projected savings from the increased utilization of your existing infrastructure must outweigh the incremental cost of own hardware. building that cloud. An alternative is to opt for a hosted private cloud, in which a hosting provider maintains the hardware; it allows you to cut your capital spending and move it to Opex.
  6. 6. MYTH MYTH:BUSTER “If my organization deploys Microsoft Online ServicesNO. 5 my role as an Exchange Administrator goes away.”JOBSECURITY FACT: The role of the Exchange Administrator does not become obsolete due to the cloud. There are still many tasks that remain on-premise. You still have to manage your users and their mailboxes. Industry-specific data retention compliance, as well as implementing custom workflows, is still your responsibility. While some tasks may no longer reside on-premise, managed cloud services free up your time to engage in more strategic roles, providing you with new opportunities.

Windows Azure facilitates a public cloud service moving some applications off-premise to the cloud. But, apart from patching those servers and physically maintaining them, all other aspects like Windows Azure my of managing applications remain in the IT Pros hands. role becomes less technical.” Monitoring, updating, integration with services such as Active Directory, security and network monitoring - these task are still required within organizations utilizing cloud services
  8. 8. MYTH MYTH:BUSTER “If Im running applications or network services onNO. 7 virtual machines, Im already doing cloud computing.”VIRTUALMACHINE = FACT:CLOUD Just having VMs doesnt mean you have launched a cloud computing environment. Yes, you are on the road to cloud computing, but are not yet reaping the full benefits. A VM must provide the ability to grow or shrink ‘compute and storage capacity’ on the fly in order to deliver service comparable to a cloud computing resource. You also need to have the ability to provide pay-as-you-go pricing to the departments in your organization to approach the cost-savings afforded by the clouds on-demand services
  9. 9. MYTHBUSTERNO. 8CLOUDTYPES MYTH: FACT: There are many types of cloud. For example, a "customer cloud", is a There is only one private cloud hosted on-premise. A "partner cloud" is another variation of kind of "cloud." the private cloud that is hosted by an outsource partner. Finally, the "public cloud," a loosely connected network of web and application services, is the most discussed variation of cloud computing, yet it involves a level of service that no providers actually deliver today. What IT Pros must take into account as they consider any cloud service is the availability of standard and familiar protocols and application stacks.
  10. 10. MYTH MYTH:BUSTER Integration issues go away when applicationsNO. 9 are outsourced to the cloud.INTEGRATION FACT: No. IT teams dedicated to application compatibility and integration play a big role for their organizations, just as they did before the cloud. While some stand-alone applications can be moved independent of other existing systems, many will require integration with on-premise as well as other cloud applications.
  11. 11. MYTHBUSTERNO. 10BENEFACTORSOF THE CLOUD MYTH: FACT: Only a small business can The benefits of cloud computing apply equally to all businesses. Many companies are making big bets on the cloud gain any cost savings today. Microsoft itself has 40 million users of its Online benefit out of Cloud Services, including large and small organizations. Also, 10,000 corporate customers are using Windows Azure, such as 3M, Computing. Siemens and T-Systems.
  12. 12. MYTH MYTH:BUSTER All you need is your credit card to start cloud computing.NO. 11GETTINGSTARTED FACT: You can begin using cloud computing services with just a credit card. This is a good way to get experience with this new frontier of services. Most cloud services provide an environment designed for getting started and developing applications. In most cases, the cloud providers offer a ‘Getting Started’ level of resource for free. Microsoft does, for example.

However, any potential savings are jeopardized by the elimination of role goes away the IT Pro’s role. There will still be a demand for skills in the security space, network with cloud management, integration skills, Active Directory and infrastructure management. computing. The IT Pro’s role will evolve as the availability of compute cycles and networked storage increase – that is a given, just as the IT role has evolved in the past. The question IT Pros must ask themselves is, ‘am I prepared to play a more strategic role in my organization?’
