10 Myths about Cloud hosting
1. Myth: Cloud is just a fad.
Truth: Cloud as a term is new, but the concepts and requisite technologies have
been evolving for years (many years in some cases). Cloud computing continues to
emerge as a game-changing technology, with high adoption rates and investment. Gartner
Research predicts that by 2012, 80% of Fortune 1000 enterprises will be paying for
some form of cloud computing services. Cloud is here to stay.
2. Myth: The cloud is not secure.
Truth: Public clouds are fundamentally multi-tenant to justify the scale and economics
of the cloud. As such, security is a common concern. Whereas the traditional security
perimeter is a network firewall, the cloud security perimeter now becomes the hypervisor
and/or underlying cloud application. So far, security in the cloud has been good,
but this is very cloud dependent and requires a solid design and operational rigor
that prioritizes security. Also, handing your data and systems to someone else requires
proper internal controls to ensure that not just anyone has access. Be sure to ask
potential cloud providers about security from technical, operational, and control
perspectives, as well as what experience they have being stewards of customer systems
and data. If the public cloud is fundamentally not secure enough, consider an on-premise
cloud, virtual private cloud, or some sort of hybrid cloud solution (see Truth #10)
that allows you to maintain the level of security you require.
3. Myth: The cloud is not reliable.
Truth: No system has 100% uptime all the time, and neither does the cloud. Given
the scale, however, cloud services are typically designed to provide high redundancy
and availability. While this same level of redundancy/availability is possible to
achieve in-house or with dedicated hosting, it's generally cost prohibitive except
for the most critical systems. The cloud enables a higher level of reliability at
a fraction of the cost.
4. Myth: Performance is a problem in the cloud.
Truth: It depends. There are different types of clouds and use cases. In many instances,
performance is higher in the cloud because there is more available capacity and
scalability. In other cases (most notably running a database server), performance
may be less than a traditional server. It's best to benchmark your application in
the cloud to determine any performance impact (good or bad). If performance is an
issue, consider a hybrid solution (see Truth # 10) that allows you to synergize
the best of both worlds: the scalability and cost efficiencies of the cloud and
the performance of dedicated servers.
5. Myth: Customers lose control in the cloud and get locked-in.
Truth: There are different types of clouds that offer different levels of customization
and flexibility. Clouds that implement standard technology stacks and are participating
in cloud standardization efforts are your best bet to enable application mobility.
Traction for open clouds is gaining momentum and the future will involve federation
between public-to-public as well as public to on-premise/hosted private clouds.
Ask your cloud provider about their participation in and vision for cloud standardization
and federation.
6. Myth: The cloud is too complex.
Truth: Again, there are different types of clouds that have differing levels of
complexity. Many clouds simplify management and involve little to no change in your
application to move it to the cloud. Other clouds offer more power and control,
but involve a change in application architecture. Simplicity and control are always
at odds and the cloud is no different. Depending on your wants, the cloud can offer
you either.
7. Myth: Pay as you go cloud pricing will cost me more.
Truth: Cloud has huge economies of scale that get passed on to the consumer. In
addition, cloud transfers what is typically CapEx (large upfront expenditures) into
OpEx (ongoing operational costs) and enables pricing to commensurate with usage.
If pricing variability and budgeting are a concern, consider a pricing plan that
offers a predictable price. Also, don't just look at raw cost. Generally, best value
solutions are superior to lowest cost. Consider all the factors including support,
customer service, reputation, reliability, etc. when measuring value.
8. Myth: The cloud is hard to integrate with existing systems.
Truth: Many applications are stand alone and can be moved independent of other existing
systems. For integrated applications that are service oriented, integration is relatively
simple. For non-service oriented applications that require tight integration, hybrid
solutions (see Truth #10) are designed to simplify integration with the cloud. As
with all integration considerations, latency is likely a concern, so transparency
about where your cloud application lives is important.
9. Myth: The cloud is not for enterprises.
Truth: The benefits of cloud apply equally to enterprises as they do to SMBs, startups
and consumers. Since enterprises are typically more risk averse, new technologies
are generally adopted by small business first. That said, overall cloud adoption
rates are increasing substantially and we are seeing enterprise adoption today.
Expect to see a significant inflection point in the next several years where cloud
is a standard enterprise fixture (see Truth #1).
10. Myth: I should move everything to the cloud.
Truth: Not all applications are suitable for the cloud. While cloud is here to stay,
it will not replace traditional hosting or on-premise deployments, but rather complement
them. There will always be situations where security requirements, flexibility,
performance or control will preclude the cloud. In those cases, a hybrid solution
involving both cloud and either traditionally hosted or on-premise servers may make
sense. Beware of vendors who promote pure cloud for ALL applications. Instead, look
for a cloud provider who can offer you hosting options that best fit your application
needs. Also, if you are a Managed Hosting customer, recognize that today, the cloud
is "unmanaged," meaning the onus for backups, patching, monitoring, etc.
is back on you should you move to the cloud. If management services are important
to you (and they probably are if you are already a Managed Hosting customer), consider
the ramifications of a move to the cloud and look for a cloud provider that will
provide the level of support and service necessary for you to be successful.
