This is part 2 of a series of articles on: ‘Cisco, IBM, HP: still a cloud of uncertainty ?'
Contrasting headlines:
- ‘Cisco, IBM, HP in Trouble, Says Credit Suisse, As Cloud Moves Past Them' is the headline we reviewed in part one
- 'HP topples Cisco to become Cloud Infrastructure equipment market leader' is also a recent headline
- But, why the contrast ? The reason depends on how you define Cloud
- Here are some simple (non technical) definitions
What is Cloud ?
- Cloud Computing (or Cloud for short) can be defined as Computing as a service that’s delivered over the internet.
- Such computing resources can be delivered on demand, across the internet and often include Storage, Servers, Networking, Data Centers & Applications
- Payment (for such Cloud Infrastructure) is usually on a metered or pay for use basis (a bit like a utility model)
There are typically 3 Cloud Services:
1) Infrastructure as a Service (IaaS):
- You’re renting the Cloud infrastructure (Servers, Storage and Networking) from a Service Provider on demand, in a Pay As You Go (PAYG) model.
- Basically you’re using somebody’s Data Center and its sometimes called Virtual Cloud, as you don’t own the equipment and software
2) Platform as a Service (PaaS):
- Developers use Tools & Cloud services here to build Applications. These Application infrastructure services are called Middleware. Database services can also be in PaaS
- Think of PaaS as the middle layer, SaaS the layer above it and IaaS the bottom (basic foundational) layer
3) Software as a Service (SaaS):
- Is Application software provided in a one to many model on a Pay for Use or Subscription basis e.g. Google for Work, Microsoft Office 365, Cisco Webex, Salesforce's suite of offerings
- Since you’re paying for using the software, rather than hiring the infrastructure it runs on, SaaS is not generally referred to as Cloud Computing infrastructure.
- It’s a Hosted Software model
Cloud Computing can be typically be deployed in 3 ways :
1) Public Cloud:
- Users don’t purchase the hardware, software or supporting infrastructure. It’s owned & managed by Providers, who’ll serve more than one customerusing that infrastructure
- Its a style of computing where you can be given rapid access to scalable & elastic IT capabilities, but in an affordable way
2) Private Cloud:
- Where infrastructure is owned & operated by one organisation, which ensures users are completely isolated from others when receiving that service.
- You have more control over virtualised resources and services. You still benefit from the efficiencies of the cloud
3) Hybrid Cloud:
- Combines Private cloud and Public cloud services.
- In practice, most companies end up managing workloads across Data Centers, Private clouds and Public clouds
IaaS and AWS:
- AWS (Amazon Web Services) is market leader in public IaaS.
- It operates at a massive scale with a multitude of innovative web services that are being expanded at a phenomenal rate
- IaaS from AWS fits the pure definition of ‘Cloud Computing as a Service’ i.e. Cloud Infrastructure that’s paid for as a utility model (where customers rent instead of having to buy the equipment & software)
IaaS vs Cloud Infrastructure Equipment Suppliers:
- Cloud infrastructure equipment suppliers like Cisco and HP Enterprises dominate the $120bn Data Center infrastructure
- Cisco & HP Enterprises primarily sell (rather than rent out) this Cloud infrastructure to enable Cloud Services deployment in line with customer preferences e.g. Hybrid Cloud
- Its a different business model to that of AWS
- Cisco doesn’t compete in Public cloud with the likes of AWS, Google and Microsoft Azure
- HP announced the abandonment of its Public Cloud IaaS offering, moving to a partner led model for customers who need Public Cloud services
'Data Center Infrastructure':
- Data Centers form the foundation of Cloud services and as such there’s been an explosion of growth in spending on Data Centre Networking, Storage & Compute
- This 'Data Center infrastructure' includes Servers, Server Operating Systems, Storage, Networking, Network security and Virtualisation software
- HP Enterprises and Cisco are dominant suppliers of Enterprise & Service Provider Data Centre Hardware respectively.
- As demand for Public Cloud has taken off, Hyperscale Data Centers are being deployed and Service Providers are spending record amounts on Data Center equipment
Hazy Cloud Comparisons:
- Clear cut comparisons on Cloud amongst suppliers can be difficult.
- For competitive reasons, suppliers don’t report a detailed breakdown of Cloud in their financial results. Also what they classify as Cloud varies
- Amazon Web Services (a hugely secretive organisation) though has actually increased transparency in its reporting recently
- Microsoft, however, has reduced the number of segments it reports on, bundling Azure (its Cloud computing platform) into a new reporting segment.
