Cloud Computing

Cloud computing is a computing term or metaphor that evolved in the late 2000s, based on utility and consumption of computer resources. Cloud computing involves deploying groups of remote servers and software networks that allow centralized data storage and online access to computer services or resources.  In simple terms the ‘cloud’ is the ability to host a software platform or service from a remote location that can be freely accessed and used anywhere via Internet access. Additionally because the cloud is a hosted service and reduces the need for physical infrastructure it is a much lower financial investment; with many cloud-based services designed as a ‘pay as you go model’. Users access cloud computing using networked client devices, such as desktop computers, laptops, tablets and smartphones. Many cloud applications do not require specific software on the client and instead use a web browser to interact with the cloud application.

Cloud Computing Models:

Infrastructure as a service (IaaS): Providers of IaaS offer computers – physical or virtual machines and other resources such as disk image library, raw block storage and file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles. IaaS-cloud providers supply these resources on-demand from their large pools installed in data centers, a hypervisor such as Xen, Oracle VirtualBox, KVM, VMware ESX/ESXi, or Hyper-V runs the virtual machines as guests. Pools of hypervisors within the cloud operational support-system can support large numbers of virtual machines and the ability to scale services up and down according to customers’ varying requirements. To deploy their applications, cloud users install operating-system images and their application software on the cloud infrastructure. In this model, the cloud user patches and maintains the operating systems and the application software. Cloud providers typically bill IaaS services on a utility computing basis: cost reflects the amount of resources allocated and consumed.

Platform as a service (PaaS): In the PaaS models, cloud providers deliver a computing platform, typically including operating system, programming language execution environment, database, and web server. Application developers can develop and run their software solutions on a cloud platform without the cost and complexity of buying and managing the underlying hardware and software layers. With some PaaS offers like Microsoft Azure and Google App Engine, the underlying computer and storage resources scale automatically to match application demand so that the cloud user does not have to allocate resources manually.

Software as a service (SaaS): In the business model using software as a service (SaaS), users are provided access to application software and databases. Cloud providers manage the infrastructure and platforms that run the applications. SaaS is sometimes referred to as “on-demand software” and is usually priced on a pay-per-use basis or using a subscription fee. In the SaaS model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. Cloud users do not manage the cloud infrastructure and platform where the application runs. This eliminates the need to install and run the application on the cloud user’s own computers, which simplifies maintenance and support. SaaS allows a business the potential to reduce IT operational costs by outsourcing hardware and software maintenance and support to the cloud provider. This enables the business to reallocate IT operations costs away from hardware/software spending and personnel expenses, towards meeting other goals. In addition, with applications hosted centrally, updates can be released without the need for users to install new software.

Cloud computing is of three types: Private Cloud (cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either internally or externally), Public Cloud (the services are rendered over a network that is open for public use. Public cloud services may be free) and Hybrid Cloud (a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models).

There was a time when start-ups had to keep aside a large portion of their capital for infrastructure. But over the past few years, Cloud has become the preferred infrastructure mode for start-ups, helping them grow and scale rapidly. Dropbox, 99 Designs, Instagram, Parse and RedBus are some of the examples where Cloud played a significant role in their success. Realizing the growth potential in this space, Cloud service providers started to lure early-stage start-ups to host their products on their Cloud platforms. Amazon, Microsoft, Google, Rackspace and IBM have specific programmes designed for start-ups, so that they can easily get started on Cloud. These technology biggies are partnering with reputed incubators and accelerators to support their portfolio companies. Microsoft has gone a step ahead and invested in its own accelerator to attract start-ups to its Azure Cloud platform.

Here are five resources for start-ups who want to join the Cloud bandwagon.

Amazon Web Services (AWS)- As one of the first Cloud platforms, AWS is the preferred platform for many start-ups across the world. It’s very common to see start-ups spin a couple of EC2 instances to launch their minimal viable products. But to make it more attractive for start-ups, Amazon has a programme called AWS Activate, which offers a slew of benefits. For a start-up that is a member of one of the accelerators, seed funds or other start-up organisations, Amazon offers free credits ranging between $1,000 and $15,000, along with technical training programmes and free business level support.

IBM- SoftLayer, an IBM company, has a start-up incubator called Catalyst. With 13 data centres in the US, Asia and Europe, it is a viable choice for start-ups. SoftLayer has partnered with incubators and accelerators around the world to support the start-up ecosystem. Eligible start-ups get $1,000 monthly credit to host their applications on SoftLayer’s infrastructure.

Google Cloud Platform- Google is not far behind when it comes to luring start-ups to its Cloud platform. With success stories like Snapchat and Rovio behind it, Google App Engine and Compute Engine are becoming the new favourites of start-ups. The Google Cloud Platform Startup Pack offers $20,000 in credits to use any component of its Cloud services platform. Google has also partnered with accelerators and incubators like to support the latter’s portfolio companies.

Microsoft Azure- Microsoft BizSpark programme is one of the oldest and popular programmes among the technology start-ups. Eligible companies get almost every piece of software that Microsoft ships, including access to Azure, its flagship Cloud platform. As a part of Microsoft Ventures initiative, it has set up exclusive accelerators in 7 cities across the world. With 82% funded start-ups behind it, the Bangalore accelerator has been a very successful one for Microsoft.
