I’ve had the opportunity to talk to many people about cloud computing at a number of conferences across Canada. I have to say that there is considerable enthusiasm about the potential of the cloud and the many opportunities that it unlocks. Unfortunately there is a lot of uncertainty that accompanies this enthusiasm and perhaps rightly so given some of the game changing approaches that accompany the familiar. Where there is uncertainty, there are well-meaning groups and individuals who, perhaps resistant to change, paint fairly negative pictures of the cloud. I’ve collected this list of top ten myths that I have heard perpetuated at conferences and provided my thoughts on why these are indeed myths.
- All cloud is on the Internet
Perhaps one of the most common myths is that for organizations to use cloud services they must use consumer oriented services available on web. It certainly doesn’t help that those companies with an internet-only service delivery model continue to push the message very hard.
In reality, cloud technologies and cloud services are available in a variety of formats: on the internet, on private networks and even within your own organizational boundaries. Many organizations are getting started with cloud technologies by building out their own “private cloud” services on their own internal networks. Even hosted cloud service providers often provide options where their services are provided over private networks to their customers. These non-internet dependent cloud services are especially important where internet connectivity may be intermittent or non-existent.
2. All cloud services are the same
Another common myth being perpetuated is the grouping of all forms of cloud services under a common umbrella and broadly applying the characteristics of one type of service to another completely different class of service. Perhaps the most common association is where consumer oriented cloud services are equated with enterprise grade cloud business services. I’ve seen music marketplaces lumped in with business collaboration sites, social networking with infrastructure services.
Not only is this broad brush approach unhelpful, it really (no, really, really) discredits any valid points made about the considerations needed for each category or class of cloud services. While admittedly the shorthand “Cloud” services has been applied across a wide variety of technologies in different ways by a variety of providers the broad-brush approach would be like describing, perhaps, the characteristics of a motorcycle (e.g. You can get wet when it rains) across all vehicles. Certainly the characteristic applies to some vehicles (bicycles, convertibles, pogo sticks) but not to others. The same is the case in cloud services. Cloud services vary considerably not only from how people consume the service (Infrastructure, Platform, Software as a service), from the business function of the service (search, database, collaboration), the business model (subscription, advertisement, licensed), from a service model (private, hosted and public) and more. Some cloud services oblige its users assemble their own functionality, where others are pre-packaged. As you look at any assessment on cloud services, be sure to explore a little further to make sure that you appreciate how that assessment applies to your particular business situation and use of cloud technologies.
3. You cannot mix and match cloud services
Modern organizations use a variety of best of class tools to address their business requirements. For some reason, a misperception that the move to the cloud is an all or nothing proposition, either from a bundling perspective or from a business application delivery perspective. This misinterpretation can hinder the adoption of cloud technologies by organizations as they look to move to these services.
Flexibility is one of the fundamental advantages of the cloud. Cloud services provide flexibility to use just what you require, when you require it. This flexibility extends into new programming models where developers have the flexibility to separate data and compute, leveraging the best locations for their operations. The interoperability built into cloud services also provides flexibility to organizations allowing reuse of internal systems, such as identity management, with external cloud services. As organizations make their move into the cloud they often adopt one or two services while keeping connections to their existing internal services.
4. Cloud Providers just toss the data into their data centers
Some presentations I’ve attended would lead you to believe that cloud service providers manage their data like an episode of the TLC’s Hoarders TV series, where data simply piles up and becomes lost.
Compliance audits, certifications, service level agreements, availability and reliability assertions all oblige enterprise grade cloud service providers to know where their customer’s data resides.
5. Cloud providers just shovel over data in response to lawful access requests
One myth that instills concern in people is the suggestion of a half hazard approach to responding to lawful access requests. Perhaps this misperception is coupled with the previous myth since naysayers could conclude that if organizations don’t know where the data is, they would simply hand over an arbitrary collection and let law enforcement sort through it.
Really? This is perhaps the stuff of movies. Enterprise grade cloud providers have considerable experience in responding to lawful access requests and strive to provide exactly the specific information being sought. And because close control is maintained over the data, cloud providers can separate only the information requested from the other data.
6. Operators casually browse the data sets in their custody
I get the impression that some people think of a data centre operator’s job as a boring day, spent in front of a relatively blank screen perhaps playing solitaire. The reason that this comes through is because of false assertion that cloud operators casually browse customer data sets.
Well, if you have a single operator and a single server it could be a rather long day. But the business of cloud computing is a business of scale. To be successful, cloud service providers need to be able to operate their computing resources at a massive scale http://tinyurl.com/2622zqt. One example of this scale is in the coverage model of operators to servers. In world class enterprise data centers the ratio of operators to servers is around 1-140. For cloud service providers that ratio jumps by an order of magnitude. I think that you can all appreciate that in today’s economic reality, enterprises can ill afford to have employees that just sit around, so one could expect that the data center operators have gainful work expected of them throughout the day. Simply put, the operators are kept busy enough maintaining the high operational availability of the cloud services that they provide that they simply would not have the time to browse the data sets. And even if they did, there are a number of internal safeguards that have been implemented to prevent this sort of misuse.
7. Law enforcement browses the cloud at service provider’s locations
Much like the aforementioned myth, a number of individuals make assertions that every use of the cloud is automatically accessed by law enforcement. There is no mention of differentiation of services, no mention of safeguards applied by consumers, no mention of the need for warrants, just a presumption of almost casual access.
Let’s take a closer look at the reality. Yes, law enforcement agencies worldwide have procedures that they can use to obtain data from cloud services providers as part of an investigation. At this year’s Federal Privacy Commissioner’s consultation on the Cloud, David Fraser highlighted the equivalences between Canadian and US lawful access procedures. Input to the Trilateral Committee on Cross Border Data flows noted that the possibility of US law enforcement using their access to obtain Canadian data is “vanishingly small”. Perhaps it’s simply “System 1” getting the best of the pundits.
8. The cloud exposes your data to incidental access
Perhaps it’s from the olden days when the high tech crime investigators literally used yellow tape, chalk lines and computer confiscation to start their investigation, but there is a myth that investigations of cloud services providers begins with wholesale confiscation of hardware.
Cloud services have been around for many years, many for well over 10 years. Both law enforcement and cloud services providers have worked together to build effective processes to provide the data required for investigation support. These processes emphasize close cooperation to provide only the data required and respect the privacy and SLAs of other customers.
9. It’s against the law in Canada to use international Cloud services
There is a common misunderstanding that there are a large number of Canadian laws that prevent the transfer of data outside of Canada extending across different business sectors both public sector and private sector.
Let me start off with a disclaimer that I am not a lawyer, so all organizations should seek competent legal advice about the compliance requirements that their organization must abide by. That said I have been deeply involved with the deployment of broad consumer cloud services in Canada, assisted Industry Canada and the Federal Privacy Commissioner in their consultations on cloud security and privacy and helped deploy cloud based services in provinces, municipalities and private sector. There is one Canadian jurisdiction with a prohibition on the storage of a specific category of data outside of Canada. The British Columbia Freedom of Information Privacy Protection Act prohibits storage or access of personal information in its custody or under its control outside of Canada. Note that this is a subset of the information held by governments in BC and doesn’t apply to the information that private sector uses for their own services. I’ve highlighted a few of the organizations that have provided advice and guidance on considerations and safeguards for use of the cloud in a previous blog post.
10. The Cloud will displace all other technologies
Rounding out the group is the myth that everything will move to the cloud and that all other technologies will be replaced. Some suggest that mainframe computers will magically disappear, local servers and internal corporate networks will vanish, and that all applications will reside in the cloud leaving local devices a shadow of their current self; supporting perhaps no more than a browser.
If we were to look at the stepwise shifts in technology in the past, for example the rise of the PC, client server computing, the advent of the web, the adoption of services oriented architecture we see how the technological shifts were additive to the existing technologies. While some workloads moved away from the previous paradigm, after an adoption period equilibrium was reached where the old and the new coexisted. Looking broadly at the cloud technologies, we see that one of the key principles behind the cloud is ubiquitous network connectivity. As cell phone users we recognize quite well the connectivity dead zones that can exist for universal coverage (ever tried to take a call from the ice rink) Certainly as we look at the broad expanse of Canada we can see that while tremendous progress is being made, there are still some regions without broadband access. Consumers and businesses need to be able to use their computing resources even when connections are not available. Apps that are only available via the web might not be the ideal solution for individuals that find themselves beyond a connection from time to time. A more realistic scenario is where your devices will be able to work regardless of location and connect when available or convenient to synchronize.
As organizations explore the opportunities of cloud computing it is critically important that they look beyond the myths and begin to focus on the specifics on the which services they are looking to use, for which data in which way.
