Cloud lock-in a bigger issue than security
Before LabSlice I was employed as a Security Architect for a major bank. Banks, government departments and health providers are naturally suspicious of technology solutions that they do not fully control. This is why cloud security is frequently listed as a concern for big industry, typically followed by operational uptime concerns. What you can’t control with your big budget is usually what you fear will backfire and cause you trouble.
But that’s not my stance. In general there is little that differentiates normal security concerns from cloud security concerns, and the big players (Amazon, Google and Microsoft) can usually deliver better security controls than most companies can achieve themselves. With certifications such as ISO 27001, annual SAS70 audits and the attainment of PCI-DSS, cloud vendors are showing themselves to have stronger datacentre controls than most companies, or at least SMBs. And true cloud computing (IaaS and PaaS) only provides you the infrastructure, not the application. It’s up to you to develop bullet-proof security for your application, by adding appropriate access control, data encryption and frequently monitoring the activities of your application.
So if the cloud is so secure, why do I have a nagging feeling about Amazon, Google and Microsoft being the biggest cloud providers around? My bet is that cloud security concerns will eventually die out, as the next generation of IT professionals start to realize that they have been playing right inside the wolf’s den. Cloud lock-in is the problem of the future.
How you will be locked in to your cloud:
1. Whilst there are some efforts to build cloud agnostic consoles and APIs, these efforts will ultimately bear little fruit. Ever-so-slight differences between cloud providers will make it difficult to extract yourself from one cloud and move to the next. One of the top cloud vendors is already well-known in the industry for locking people into their solutions, and there should be no difference in how they play out their business model in the cloud.
2. Cloud vendors are not your standard host providers (eg. GoDaddy). Rather, the large cloud providers are already well-established players in multiple industries. Consider that players like Google are providing you a very easy platform on which to build the next social application, whilst at the same time they are trying very hard to enter this market themselves. In many ways I see cloud providers owning a platform that helps them deliver services they want to own in the future, and it’s no surprise that the 3 major players are strongly targeting startups. I don’t see a company like Google allowing the next Facebook or Twitter to easily migrate their platforms away. The bigger you get, the more hurdles you will find when you talk to your cloud vendor about migrating away.
3. When you use a cloud vendor today you are not just buying compute power. Rather, you are building on top of a compute stack selected by the vendor, from the operating system right through to the programming languages made available (even IaaS locks you in to certain stack decisions). Migrating from one application stack to another is never an easy task.
My bet… Within 5 years you will hear little about cloud security, but you will find a lot more companies stuck with vendors that they would prefer they didn’t select to use today.
