If you believe in the momentum, it’s time to give digitalocean a try!!! A new digitalocean promo code is available for new customers for May 2014!

Go @ digitalocean website and sign up

To get your first Droplet going (Digital Ocean’s name for a VPS deployment) you have to enter your billing details as well as hand over your credit card. Digital Ocean actually offers per-hour billing for all their VPS offerings, so the credit card information is taken just to ensure they can bill you at the end of the month. By the way my choice of payment was through paypal! I added 10$ for the first two months.

Now after confirming your account you can add this promo code:

SSDMAY10

and you will get 10$ free!!!

Go at digitalocean right now and use the above promo code, add 10$ more to your billing and you will have 4 months to try digitalocean and become a fan!!!

The reasons I like digitalocean:

Clean and Easy to Use Control Panel

A friendly interface to control all of your virtual servers. Create, resize, rebuild, and snapshot with single clicks. I also like the DNS management section in Control Panel, that provides an excellent way to manage delegated dns zones!

Linux Distributions & One-Click Install Apps

All of your favorite Linux distributions are supported, including the all new Ubuntu 14.04. Additionally, install your favorite applications on your cloud server with a click of a button. When creating a droplet, just click on the ‘Applications’ tab and your app will be live on your droplet in 55 seconds.

SSD-Only Cloud

Digitalocean has created the fastest and most convenient cloud technology to help you easily and more efficiently manage your infrastructure so you can get back to coding. I am fan of their high-performance SSD Hard Drives, flexible API, and the ability to select to nearest data center location. I cannot believe that it’s an SSD-Only Cloud.

Cloud computing basic service models and deployment methods

The Cloud computing model leverages virtualization to deliver computing resources to users on-demand, and possibly on a pay-per-use basis. It provides the properties of self-service, that means that each user is forced to control the resources that he needs, and elasticity enabling users to dynamically and flexibly adjust their resource consumption according to the current workload. These properties of the Cloud computing model allow one to avoid high upfront investments minimising the expenses in a computing infrastructure, thus reducing the time to market and facilitating a higher pace of innovation.

Introduction

In this article, we will try to give some definitions to some frequently used but not so frequently explained basic concepts of cloud. In this article we will describe the basic service models of cloud computing, and their deployment methods.

Cloud Computing

The Cloud computing model leverages virtualization to deliver computing resources to users on-demand, and usually on a pay-per-use basis (depending on deployment method). It provides the properties of self-service, that means that each user is forced to control the resources that he needs,  and elasticity enabling users to dynamically and flexibly adjust their resource consumption according to the current workload. These properties of the Cloud computing model allow one to avoid high upfront investments minimising the expenses in a computing infrastructure, thus reducing the time to market and facilitating a higher pace of innovation.

Basic Service Models

Cloud computing resources are delivered to users through three basic service models:

  • Infrastructure as a Service (IaaS): computing resources are delivered in the form of Virtual Machines (VMs). A VM provides to the user a view of a dedicated server. The user is capable of managing the system within a VM and deploying the required software. Examples of IaaS are Amazon EC2 and Google Compute Engine.
  • Platform as a Service (PaaS): the access to the resources is provided in the form of an Application Programming Interface (API) that is used for application development and deployment. In this model, the user does not have a direct access to the system resources, rather the resource allocation to applications is automatically managed by the platform. Examples of PaaS are Google App Engine and Microsoft Azure.
  • Software as a Service (SaaS): application-level software services are provided to the users on a subscription basis over the Internet. Examples of SaaS are Salesforce.com and applications from the Amazon Web Services Marketplace.

Deployment Methods

Apart from the service models, Cloud computing services are distinguished according to their deployment models. There are three basic deployment models:

  • Public Cloud: computing resources are provided publicly over the Internet based on a pay-per-use model.
  • Private Cloud: the Cloud infrastructure is owned by an organization, and hosted and operated internally.
  • Hybrid Cloud: computing resources are provided by a composition of a private and public Clouds.

Public Clouds, such as Amazon EC2, have initiated and driven the industrial adoption of the Cloud computing model. However, the software platforms utilized by public Cloud providers are usually proprietary disallowing their deployment on-premise. In other words, due to closed-source software, it is not possible to deploy the same software platform used, for example, by Amazon EC2 on a private computing infrastructure. Fortunately, there exist several open source Cloud platforms striving to address the issue, such as OpenStack, Eucalyptus, OpenNebula, and CloudStack. The mentioned projects basically allow anyone to not only deploy a private Cloud environment free of charge, but also contribute back to the development of the platform.
