Cloud Computing: Understanding Infrastructure as a Service

Introducing the notion of an alternative to AWS: Cloudcenters

Cloudcenters provide the same kinds of tools that all datacenter and server operators are already accustomed to, but with all the traditional advantages of cloud (i.e. self-service, pay-as-you-go, and scalability). Instead of creating completely new paradigms, cloudcenters are a methodology by which the customer can have a virtual datacenter hosted ‘in the sky.’

Amazon’s Web Services (AWS) is not the only way to build scalable Cloud Infrastructures. There are two emerging methodologies for constructing Infrastructure-as-a-Service (IaaS) AKA “Cloud Infrastructure Services”. The first is what we call “cloudcenters”, which are essentially datacenters in the sky. The second is what we call an “Infrastructure Web Service”. GoGrid was one of the pioneers for cloudcenters, while AWS largely created the second model.

Understanding IaaS means looking closely at these two approaches. Clearly the notion of cloudcenters embodied by AWS competitors such as ourselves, FlexiScale, ElasticHosts, AppNexus, and others is important. My colleague, Michael Sheehan, will go into more depth on how we think this distinction modifies his earlier Cloud Pyramid (above left) in a follow-on article to this one.

Infrastructure Cloud Models

Understanding these two approaches is important because it directly affects your selection of a Cloud Infrastructure provider. These two models highlight a difference in core infrastructure and in target markets. Cloudcenters provide a direct equivalent to traditional datacenters and hence are usually more desirable for IT staff, systems operators, and other datacenter savvy folks. Infrastructure Web Services on the other hand are more analogous to Service-Oriented-Architectures (SOA), require significant programming skills, and are much more comfortable for software developers.

Infrastructure Web Services

I’m going to assume for this article that you are somewhat familiar with Amazon Web Services (AWS), but I’ll briefly re-cap. AWS provides a number of different ‘Web Services’ that can consumed individually or put together to support different kinds of applications, usually a batch processing or web application of some kind. These services include:

  • Object-based file storage via Simple Storage Service (S3)
  • Servers on demand via Elastic Compute Cloud (EC2)
  • Block storage on demand via Elastic Block Storage (a part of EC2)
  • Distributed database functionality via SimpleDB (SDB)
  • Content distribution and edge-caching via CloudFront
  • Messaging & queuing via Simple Queuing Service (SQS)
  • Payment processing via Flexible Payment Services (FPS)
  • Billing & re-packaging of the above services via Amazon Dev Pay

This is a robust ecosystem of services form which you can use any or all of in order to build your application, getting the traditional benefits of Cloud Computing such as self-service, pay-as-you-go, and massive scalability.

Unfortunately, every service above is based on an Amazon standard, not an industry standard.  S3 is not accessible via CIFS or NFS. EC2 provides Xen hosting, but image management and storage is completely custom. SQS does not use any standard queuing or messaging protocols such as JMS or STOMP. SimpleDB now has an ‘SQL-like’ interface, but is essentially a 100% ground up creation of Amazon.

A major advantage of using the Amazon approach however is that greenfield applications developed from scratch have a very powerful set of vetted, scalable services, that can be used to build that application. This means avoiding the intrinsic and extrinsic costs associated with deploying a separate queuing or database system.

The alternative, of course, is to use the same tools, paradigms and standards that you deploy in an industry standard Enterprise datacenter today.

DevOps has traditionally played important roles in development and IT operations, but the practice is quickly becoming core to other business functions such as customer success, business intelligence, and marketing analytics. Modern marketers today are driven by data and rely on many different analytics tools. They need DevOps engineers in general and server log data specifically to do their jobs well. Here’s why: Server log files contain the only data that is completely full and accurate in th...
Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...
Several years ago, I was a developer in a travel reservation aggregator. Our mission was to pull flight and hotel data from a bunch of cryptic reservation platforms, and provide it to other companies via an API library - for a fee. That was before companies like Expedia standardized such things. We started with simple methods like getFlightLeg() or addPassengerName(), each performing a small, well-understood function. But our customers wanted bigger, more encompassing services that would "do ...
Whether you like it or not, DevOps is on track for a remarkable alliance with security. The SEC didn’t approve the merger. And your boss hasn’t heard anything about it. Yet, this unruly triumvirate will soon dominate and deliver DevSecOps faster, cheaper, better, and on an unprecedented scale. In his session at DevOps Summit, Frank Bunger, VP of Customer Success at ScriptRock, will discuss how this cathartic moment will propel the DevOps movement from such stuff as dreams are made on to a prac...

The pricing of tools or licenses for log aggregation can have a significant effect on organizational culture and the collaboration between Dev and Ops teams. Modern tools for log aggregation (of which Logentries is one example) can be hugely enabling for DevOps approaches to building and operating business-critical software systems.

Docker containerization is increasingly being used in production environments. How can these environments best be monitored? Monitoring Docker containers as if they are lightweight virtual machines (i.e., monitoring the host from within the container), with all the common metrics that can be captured from an operating system, is an insufficient approach. Docker containers can’t be treated as lightweight virtual machines; they must be treated as what they are: isolated processes running on hosts....
