re: Top 12 Cloud Trends Of 2012
This is a great article for Cloud trends. I particularly like #7 which talks about the large use of Cloud for DR. I also found another relevant article on DR in the Cloud here http://www.fracrack.com/blog/2...

re: Top 12 Cloud Trends Of 2012
Cloud = mainframe. We are going backwards with new buzzwords. All these years coding for distributed servers and we are going back to consolidated operating systems with multiple cores. Mainframes - yay - I used to work on them. At least with mainframes you had the option to keep your data in house behind your own protection. With the cloud anyone can take a crack at it. Today companies like verisign are being hacked daily and they are supposed to be trust authorities. How safe do you think your data will be on a mainframe (sorry, cloud) that is accessible by millions of people. When anon get a hold of an administrator password it will not matter how compartmentalized your data is. At least when you are behind hardline firewalls your are not subject to random hacks "I pick you pikachu". The hackers have to be in the same geographical location, have access to your hard lines, have the technical ability to both hack your comms and hack your encryption (a rare combination). For any company where every transaction means money (Banks, stock exchanges, clearing houses etc.) doing business in the cloud is clear insanity. For music stores and book sales, go for it. It saves a lot on infrastructure costs. Shared mainframe time. Also if a music store goes down it means 10,000 people out of a job, not an entire bank and all of it's investors out of their homes. Also don't trot out the adage that the data is encrypted, everyone knows that the data cannot be attacked directly. They attack the people with the passwords to the data. Key loggers etc. It takes one little mistake in the wee hours of the morning when you are half awake to accidentally load a key logger. One person in your trust chain gets compromised and you may as well not have encryption. Why? Because encryption keys should be cycled. But they aren't. They are normally hard coded, because they are a pain to change. All it takes is one annoyed exeployee and you may as well be sending clear text. DES has been compromised. MD5 look up sum tables are prevalent, it may not be your password, but it ends up appearing the same to a computer due to failures in the MD5 hash algorithm. So the attacker does not need your password, he needs the sum of your password, he needs your encrypted data - and with your encrypted data he can decrypt the rest of your data. Maintaining decent solid, rapidly changing security is beyond our current programming models. The hackers are ahead of us on this one, and until we catch up there will be a lot more hacking to come.
Back on topic - I realize I deviated but i will leave it because it seriously applies to the whole 'cloud' / 'mainframe' concept. If you are a little startup by all means go cloud. If you deal in billions - I would stay away and hire a good CIO.

Good post especially point 8 on the SLA detente.

With nearly all of the Cloud Providers that I've worked with as s Consultant it's amazing how their SLAs are only centred around uptime and availability. This is quite ironic in that you wouldn't buy a PC for example based on the fact that it will turn on and stay turned on when its performance is atrocious!

It is here where I think the Cloud will certainly need to mature as more and more critical applications are considered for it. SLAs need to be refined around performance metrics as opposed to just uptime and availability.

With the company that I work for namely Virtual Instruments we can uniquely measure the infrastructure performance of critical applications deployed in the cloud by looking across the SAN fabric. What we've found to be incredibly successful is enabling our Cloud provider clients to in fact mature their SLAs based on performance metrics such as response times.

We've also helped these Cloud Providers to help establish SLAs for their end users who didn't necessarily have any in place for their low tier apps. This has been a clear differentiator for them in gaining new customers and convincing them to deploy more key applications into the Cloud.

From what I'm seeing 2012 will certainly be the year where Performance will take more precedence in the drive towards the Cloud and that means a better grasp of SLA distinction and definition.

One of the issues with cloud computing and addressed in the article is scale -- and sharding of data is increasing as a way to deal with this problem. We've got a general blog post on what database sharding is and how it can be implemented. (http://www.scalebase.com/datab...
