Cloud - What is it?
Transcript of Cloud - What is it?
Increase / decrease your site based on usage
Reduce the risk of initial purchase Startups
Reduce cost of development environment
Servers on the cloud (also SAAS for email, file server, etc..) R&D
Development & Testing labs.
Easily create images, sandbox for developers, integration systems, test environments, customer environments, etc.…. Enterprise IT
Reduce cost of ownership
next step after outsourcing IT But what does it really mean?
It sounds like just a new buzzword – it will die soon
Is it really new?
I used hosting services for a long time now, what’s the difference?
Isn’t it just the same as a virtual server which I used in my lab?
This is good for web service providers, not for me
Tried to look at it once, too many information and I got lost What does it actually mean? Is it really different? Is it new? Why now? Ok, what's in it for me? What do I pay for? And how much Who are
the main players? How do I decide between them? i heard lots of buzzwords – What does it all mean? Is it reliable? (http://cloudcomputing.sys-con.com/node/579826) Infrastructure as a service
Public service over the Internet
Ability to expand/reduce the amount of computing power at a will (Elastic)
Paying only for what you actually use Virtualization The technical infrastructure of a cloud service uses virtualization. But the cloud service provides a lot more on top of it. Service it provides the infrastructure, you decide what service you run on it. It is confusing since many service providers (e.g., salesforce.com run their service on a cloud. Using their service does not mean you use the cloud) Hosting provider can use or not a virtualization (or cloud) as its infrastructure. The offering of hosting service provides a pre-defined server. Hosting is not elastic. Hosting Technology Business model Maturity i heard about it xxx... As A Service Software As A Service (SAAS): software service that is provided over the Internet. This can be a mail service, waze, Greenroad, Prezi and many many more.
Platform As A Service (PAAS): Usually refers to hosting service which provides platforms to the users who develop their application on top of this platform. Example can be google sites (or docs.), salesforce.com, and more.
Infrastructure As A Service (IAAS) – this is the cloud service which provides you with the infrastructure to run whatever you wish. go, grow, use: You pay for what you actually use rather then for purchasing/booking resources.
You do not have to pre-order…
You do not have to commit up-front
You are not sure how much you will pay at the end of the month.... Public, Private, Hybrid hybrid…
Public and Private combined.
The organization uses private cloud and in pick uses (or other criteria) will also use service from the public cloud. Until 2 months ago … I would say – certainly yes. Large, reliable, companies
Their main business is "to be reliable" Amazon had 2 days outage! This is the first time that an outage
at this scale has happened. Server: CPU, RAM, Disk
Bandwidth – in/out
in some: Operating System (windows)
Based image such as Dbase
Network services: Fixed IP, VLAN
Management: Monitoring, Backups, …. Pricing examples Some Links:

Cloud vendors (updated Apr. 08): http://www.johnmwillis.com/cloud-computing/cloud-vendors-a-to-z-revised/
85 vendors…. (Aug. 09): http://itmanagement.earthweb.com/features/article.php/12297_3835941_2/85-Cloud-Computing-Vendors-Shaping-the-Emerging-Cloud.htm First step: Analyze and define your needs Infrastructure: Supported OS, supported services (Dbase, web service, application service, Queue server, etc.)
Interface: User (Web), API, Image creation, automation?
Management services: Backup, alerts, …
Network specific requirements, Physical location/distribution
Bandwidth (how much do you need to send in/out – how long will it take?)
Pricing (based on your need – servers, storage, services and… don’t neglect the bandwidth) Possible criteria's for cloud selection: Technology Business model Virtualization maturity
Small number of different OSs (Windows, Windows, Windows and Linux)
Large players can reduce the price of purchase and ownership to a level that they can provide it to others
Natural evolution of SAAS, PAAS…
Outsourcing the IT services has become more common Maturity Focus on R&D (http://en.wikipedia.org/wiki/Cloud_computing) "... the computer units no longer resides in the user’s premises..." (http://searchcloudcomputing.techtarget.com/definition/cloud-computing) "... anything that involves delivering hosted services over the Internet ...." "... In essence this is distributed computing..." But they all refer to a HW infrastructure which serves as resource to different software services where the actual HW and SW are oblivious to one another. There are many, some contradictory, definitions… In this presentations, we focus on: Is it new? Why now? 3 Elements to consider: Internet connection speed Virtualization maturity management tools
Security Service for the big guys Service for middle class companies Service for web service providers Service for start-ups Service for small offices Service for home users? 3 Elements to consider: Is it new? Why now? All 3 are in place Pay are you... Public a Cloud service provided over the Internet for multiple customers/users Private A cloud server that serves a single organization - the owner of the cloud.
Can reside on the Internet or locally in the organization’s premises (assuming this is a large organization, it is probably anyway distributed over the internet).
This is not new and in my view, uses the cloud enhance management (and virtualization) technologies for local use.
I personally do not see it as a cloud.. Hybrid Amazon, Google, Misrosoft, Salesfoce Rackspace, GoGrid, Flexiscale, Elastic Hosts, many more Israeli based cloud: Microsoft We! Hosting providers (clubVPS, Webox, .....) Lots of services on top of cloud
- Data storage
- Data management
.... Players Technology Business model Maturity Replace large IT farms HW extension for pick usage Extend local farms in busy hours Test new initiative with low risk TripleC But... Many sites, some very popular were down!!
Some very popular sites - Foursquare, Quora No big surprise here.. and more... Cloud services Is it the last?
