Oracle 11g Database in the Cloud

Tuesday, February 8th, 2011

Amazon Web Services said earlier today that its plans to add the Oracle 11g database to its cloud hosting services this year. This will enable users “to perform relational tasks and development work on an on-demand hourly basis.”

Unveiled on Amazon Relational Database Services running Oracle Database web page to educate potential users about the service. The website also enables those interested to sign up to be notified when the service goes live.

“Customers were really excited when we launched Amazon RDS for MySQL because it allowed them to run familiar MySQL databases while offloading the operational responsibilities and capital costs associated with physical servers and datacentres,” Raju Gulabani, vice president of database services at AWS said in a statement.

“Enterprises asked when we will offer the same functionality for Oracle databases. We are pleased to share that we are not only releasing it soon, but are ready to have conversations with interested customers so they can plan for future deployments.”

We’ll see what the new Oracle 11g cloud hosting solution does for the average person, but I believe that it’ll help a lot of people out!

Amazon Cloud Hosting vs Rackspace Cloud Hosting

Friday, November 5th, 2010

Cloud hosting has become a powerful and affordable option for those who need access to server resources on a dynamic basis. While relatively new, the technology itself is proven and already there are many well-established companies moving into the Cloud hosting space.

Two of the biggest names are Amazon and Rackspace, and the Amazon Cloud and Rackspace Cloud offerings both take the lead in this growing market. Both offerings tout the ability to create new server instances within minutes, to scale up and down almost immediately as your requirements change, and the advantage of paying only for capacity used. And true enough, both companies do exceptionally well in that regard. Users of either offering have consistently gained advantage, and both are highly acclaimed.

The Rackspace Cloud does offer an edge in a few areas though, especially in persistence of the virtual server. Because the Rackspace offering is tied to RAID10 disk storage, you do have additional protection against a drive failure in case of a failed host. In other words, if an unlikely server failure does occur in the Rackspace facility, your own Cloud Server will still exist. Depending on your particular data center needs, you may wish to embark on a hybrid strategy of Cloud and dedicated servers. Not everybody needs such a strategy, but it may be necessary for example in the case of a company with both a highly secure private, as well as public intranet. In such a case, Rackspace again does give you the option of dedicated servers as well. While Cloud hosting, and Cloud computing in general, is typically very easy to implement and to operate on a day-to-day basis, support remains an important consideration, especially since the physical server is removed from your own premises. You rely on your provider to provide ongoing support. Amazon does offer a paid premium support package in addition to its basic tech support service, which gives you fast support.

Rackspace takes a different approach with its “Fanatical Support” offering, which comes free with every Cloud hosting account. Without the added layer of paid support, even with everything else being equal Rackspace would come in at a lower price point. Finally, those who want to start small may also want to give Rackspace a top space on your short list, with Cloud Servers starting at just 256MB and going up to 16GB.

pros/cons of Amazon vs. Rackspace Cloud.

Rackspace Cloud:-

  • Speed & usability of the web interface:, It would be nice to have a few more features in the web interface, such as the ability to launch multiple servers at once
  • Multiple data center support: the ability to choose a specific data center for each instance that is provisioned.
  • A directly attached storage solution: although the disk space allotted to each instance is reasonable, non-volatile, and fast, there’s no ability to expand for increased storage or setup logical RAID volumes for increased throughput.
  • Custom image support: it would be nice to run FreeBSD (version 8.x has good support for the Xen hypervisor).

Amazon Cloud:-

It is the most well-known provider, and for good reason.  They have a strong API, flexible implementation options, “external” storage, and a slew of other features.  Here are some things to be improved:

  • Static internal IP addressing: unlike Rackspace Cloud, EC2 doesn’t guarantee that your internal IP address and/or DNS entry won’t change.  This can be a hurdle for those that want to implement internal DNS.  However, EC2 is smart enough to re-route traffic to other EC2 instances locally at all times, even if the public IP address is used.
  • Security groups can’t change: once an instance is launched, you can not change its security group configuration.  This hinders flexibility.
  • Buggy Amazon Cloud console: the console that is provided by Amazon is buggy.  One example: sometimes security group rules will disappear if you attempt to access a security group you’ve modified during the same session.
  • Lack of clarity on data center/zone locations: this can hurt standard naming conventions (such as after airport codes) when you don’t know exactly where your instances are located.

Let’s take a look at the various areas that a consumer should care about, starting with one of the more important areas:


Pricing is important.  You’re talking about pay-on-demand server resources, so you want them to be economical.  You also want the long-term pricing model to be competitive to dedicated servers, so you don’t have to spread things between providers.  All prices are for basic Linux (Ubuntu 10.04), both services also offer Windows servers (at a higher price) and other Database options.

Amazon EC2

Amazon provides multiple Instance options, depending on what you need:

  • Small Instance (the default):  1.7GB of RAM, 1 CPU Core, 160GB of Storage, 32-bit platforms only
  • Large Instance:  7.5GB of RAM, 2 virtual cores, 850GB of Storage, 64-bit platforms (and 32-bit if you wish)
  • Extra Large Instance:  15GB of RAM, 4 virtual cores, 1.7TB of Storage, 64-bit platforms (and 32-bit if you wish)

Note:  Amazon EC2 also can provide High-Memory, High-CPU, and Cluster capable Instances (not covered here). These various options come in 3 different Pricing Options:

  • On Demand – Pay by the hour that the Instance is running ($0.085/hour for Small, $0.34/hour for Large, $0.68/hour for Extra Large)
  • Reserved – Pay by the year ($227.50/year for Small, $910/year for Large, $1820/year for Extra Large), additional discounts for additional years
  • Spot – These are different, you specify a maximum you’re willing to pay/hour and as long as the price is below that, you get it.  If the price increases (because demand for these types of Instances is growing) above your maximum, the Instance is terminated.  Since the prices fluctuate, $0.031/hour for Small, $0.14/hour for Large, $0.233/hour for Extra Large (about 1/3 of an On Demand at the moment)

Rackspace Cloud

Rackspace Cloud doesn’t have nearly the complexity in picking an Instance, but they do give you more granularities in the configuration (and price):

  • 256MB RAM, 10 GB Disk:  $0.015/hour
  • 512MB RAM, 20 GB Disk:  $0.03/hour
  • 1024MB RAM, 40GB Disk:  $0.06/hour
  • 2048MB RAM, 80GB Disk:  $0.12/hour
  • 4096MB RAM, 160GB Disk:  $0.24/hour
  • 8192MB RAM, 320GB Disk:  $0.48/hour
  • 15872MB RAM, 620GB Disk:  $0.96/hour

A Quantitative Comparison of Rackspace and Amazon Cloud Space

1) RSC’s storage is directly attached and persistent. This means fast I/O, and that you don’t (necessarily) lose your data in the event of a crash or reboot. To get persistence with EC2 you have to pay for one or more EBS volumes, and they’re still not directly attached.

2) Where Amazon gives you ceilings, RSC gives you floors. EC2 says “This is how much CPU you get,” while RSC says “You’ll get at least this much CPU, and you can burst if there’s more available.”

3) A much better scaling model. If you need to scale on EC2, you have to launch additional instances (which you can do with stored AMI’s). At RSC, you can point to a running instance and click a button to say “Make this server bigger” (or smaller if you need to scale down). A few minutes later, it’s all done.

4) Support! Amazon has pay-per-incident support. If you’re using Cloud Sites, Rackspace sysadmins manage your instance(s) for you. If you’re using Cloud Servers, you manage your own instance(s) but still get their support* which really is as good as they say it is.

5) Hybrid deployments. For larger deployments you can mix-and-match VPS instances and dedicated hardware, and they’ll work pretty seamlessly together. Amazon doesn’t offer this at all.

6) DNS and reverse DNS. DNS services are common (though EC2 doesn’t offer them), but reverse DNS is unheard of. If you look up my host’s IP you get back my hostname instead of some convoluted hostname set by my hosting provider.

How Big is Amazon’s Cloud Computing Business?

Tuesday, August 3rd, 2010

How big is Amazon Web Services (AWS) cloud hosting business? I have been doing a little research about the cloud services giant and here is some of the numbers that I got.

UBS Investment Research analysts Brian Pitz and Brian Fitzgerald released a report which puts revenue numbers of the giant cloud hosting company Amazon’s web services. The duo estimate that in 2010, AWS will generated about $500 million in revenues and will grow this to $750 million by 2011. By 2014, it would bring in close to $2.54 billion in revenues.


UBS analysts believe believe that the total market for AWS type services will be between $5-to-$6 billion in 2010 and will eventually grow to $15-to-$20 billion in 2014. How do they arrive at these numbers?

  • IDC says the total global cloud market in 2010 will be $22 billion and $55 billion in 2014.
  • IDC says of the total servers and storage account for $5 billion-to-$6 billion in 2010 and $15-to-$20 billion in 2015.
  • Of the twelve AWS product lines, only two (EC2 and S3) compete in this subcategory. AWS essentially ‘rents out’ IT infrastructure to companies that seek to outsource IT needs such as Application Hosting, Web Hosting, High Performance Computing, Storage, E-Commerce, and more. Amazon was one of the first entrants (3Q06), and is a top player in the rapidly growing market. (UBS Research Report)

Can anyone else say that they are a giant in the cloud hosting space.  I sure wish that I was one of the first people to start cloud computing.  I’m still stuck with my 5 dedicated servers all across the US and UK! So question to our readers, do you really think that $2.5 billion dollars is possible in the next 3 years?  Do you think that AWS cloud hosting services can produce that much revenue in the next 3 years?
