Applications of Cloud computing in Bangladesh Cloud computing is currently one the most hyped IT innovations that promises potential opportunities for business and social innovation as well as modernizing ICT. For developing countries like Bangladesh, this technology aims to provide the clients a cost effective and convenient means to manage the huge amount of IT resources and thus offer strong possibility of accelerating social and economic development, even in this time of limited resources. As the information technology industry goes through a major shift, founded on the Internet as a platform, new opportunities for Bangladesh are open to employ technology at a lower cost and with much greater ease and success than in the past. Cloud Computing In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer’s hard drive. The cloud is just a metaphor for the Internet. Cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics and more—over the Internet (“the cloud”). Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you are billed for water or electricity at home. Let’s be clear here. We’re talking about cloud computing as it impacts individual consumers—those of us who sit back at home or in small-to-medium offices and use the Internet on a regular basis. There is an entirely different “cloud” when it comes to business. Some businesses choose to implement Software-as-a-Service (SaaS), where the business subscribes to an application it accesses over the Internet. (Think Salesforce.com.) There’s also Platform-as-a-Service (PaaS), where a business can create its own custom applications for use by all in the company. And don’t forget the mighty Infrastructure-as-a-Service (IaaS), where players like Amazon, Microsoft, Google, and Rackspace provide a backbone that can be “rented out” by other companies. (For example, Netflix provides services because it’s a customer of the cloud services at Amazon.) Of course, cloud computing is big business: The market generated $100 billion a year in 2012, which could be $127 billion by 2017 and $500 billion by 2020. Top benefits of cloud computing: Cloud computing is a big shift from the traditional way businesses think about IT resources. What is it about cloud computing? Why is cloud computing so popular? Here are 6 common reasons organisations are turning to cloud computing services: - Cost Cloud computing eliminates the capital expense of buying hardware and software and setting up and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, the IT experts for managing the infrastructure. It adds up fast. - Speed Most cloud computing services are provided self service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning.3. Global scale The benefits of cloud computing services include the ability to scale elastically. In cloud speak, that means delivering the right amount of IT resources—for example, more or less computing power, storage, bandwidth—right when its needed and from the right geographic location. - Productivity On-site datacenters typically require a lot of “racking and stacking”—hardware set up, software patching and other time-consuming IT management chores. Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals. - Performance The biggest cloud computing services run on a worldwide network of secure datacenters, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scale. - Reliability Cloud computing makes data backup, disaster recovery and business continuity easier and less expensive, because data can be mirrored at multiple redundant sites on the cloud provider’s network. Types of cloud services: Most cloud computing services fall into three broad categories: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (Saas). These are sometimes called the cloud computing stack, because they build on top of one another. Knowing what they are and how they are different makes it easier to accomplish your business goals. Infrastructure-as-a-service (IaaS) The most basic category of cloud computing services. With IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis. Platform as a service (PaaS) Platform-as-a-service (PaaS) refers to cloud computing services that supply an on-demand environment for developing, testing, delivering and managing software applications. PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network and databases needed for development. Software as a service (SaaS) Software-as-a-service (SaaS) is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching. Users connect to the application over the Internet, usually with a web browser on their phone, tablet or PC. Types of cloud deployments: Public cloud Public clouds are owned and operated by a third-party cloud service provider, which deliver their computing resources like servers and storage over the Internet. Microsoft Azure is an example of a public cloud. With a public cloud, all hardware, software and other supporting infrastructure is owned and managed by the cloud provider. You access these services and manage your account using a web browser. Private cloud A private cloud refers to cloud computing resources used exclusively by a single business or organisation. A private cloud can be physically located on the company’s on-site datacenter. Some companies also pay third-party service providers to host their private cloud. A private cloud is one in which the services and infrastructure are maintained on a private network. Hybrid cloud Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public clouds, hybrid cloud gives businesses greater flexibility and more deployment options. Uses of cloud computing Cloud computing has been credited with increasing competitiveness through cost reduction, greater flexibility, elasticity and optimal resource utilization. Here are a few situations where cloud computing is used to enhance the ability to achieve business goals. - Infrastructure as a service (IaaS) and platform as a service (PaaS) When it comes to IaaS, using an existing infrastructure on a pay-per-use scheme seems to be an obvious choice for companies saving on the cost of investing to acquire, manage and maintain an IT infrastructure. There are also instances where organizations turn to PaaS for the same reasons while also seeking to increase the speed of development on a ready-to-use platform to deploy applications. - Private cloud and hybrid cloud Among the many incentives for using cloud, there are two situations where organizations are looking into ways to assess some of the applications they intend to deploy into their environment through the use of a cloud (specifically a public cloud). While in the case of test and development it may be limited in time, adopting a hybrid cloud approach allows for testing application workloads, therefore providing the comfort of an environment without the initial investment that might have been rendered useless should the workload testing fail. Another use of hybrid cloud is also the ability to expand during periods of limited peak usage, which is often preferable to hosting a large infrastructure that might seldom be of use. An organization would seek to have the additional capacity and availability of an environment when needed on a pay-as you-go basis. - Test and development Probably the best scenario for the use of a cloud is a test and development environment. This entails securing a budget, setting up your environment through physical assets, significant manpower and time. Then comes the installation and configuration of your platform. All this can often extend the time it takes for a project to be completed and stretch your milestones. With cloud computing, there are now readily available environments tailored for your needs at your fingertips. This often combines, but is not limited to, automated provisioning of physical and virtualized resources. - Big data analytics One of the aspects offered by leveraging cloud computing is the ability to tap into vast quantities of both structured and unstructured data to harness the benefit of extracting business value. Retailers and suppliers are now extracting information derived from consumers’ buying patterns to target their advertising and marketing campaigns to a particular segment of the population. Social networking platforms are now providing the basis for analytics on behavioral patterns that organizations are using to derive meaningful information. - File storage Cloud can offer you the possibility of storing your files and accessing, storing and retrieving them from any web-enabled interface. The web services interfaces are usually simple. At any time and place you have high availability, speed, scalability and security for your environment. In this scenario, organizations are only paying for the amount of storage they are actually consuming, and do so without the worries of overseeing the daily maintenance of the storage infrastructure. There is also the possibility to store the data either on or off premises depending on the regulatory compliance requirements. Data is stored in virtualized pools of storage hosted by a third party based on the customer specification requirements. - Disaster recovery This is yet another benefit derived from using cloud based on the cost effectiveness of a disaster recovery (DR) solution that provides for a faster recovery from a mesh of different physical locations at a much lower cost that the traditional DR site with fixed assets, rigid procedures and a much higher cost. - Backup Backing up data has always been a complex and time-consuming operation. This included maintaining a set of tapes or drives, manually collecting them and dispatching them to a backup facility with all the inherent problems that might happen in between the originating and the backup site. This way of ensuring a backup is performed is not immune to problems such as running out of backup media , and there is also time to load the backup devices for a restore operation, which takes time and is prone to malfunctions and human errors. Cloud-based backup, while not being the panacea, is certainly a far cry from what it used to be. You can now automatically dispatch data to any location across the wire with the assurance that neither security, availability nor capacity are issues. Application of Cloud computing in Bangladesh Cloud computing and cloud services offers potential advantages to the customers in developing countries like Bangladesh. As the cloud computing ecosystem evolves, the organizations and companies from the developing world should consider these offers. These potential offers are the great opportunities for the developing nations to grow their business in a significant manner. These offers include: - Reduced costs for rented IT hardware and software compared to in-house equipment and IT management. - Enhanced elasticity of storage/processing capacity as required by demand. - Greater flexibility and mobility of access to data and services. - Immediate and cost-free upgrading of software. - Enhanced reliability/security of data management and services. Cloud computing adoption speed in Bangladesh is not equal to world cloud adoption speed. Limited companies in Bangladesh are working on cloud service provision. Cloud computing strengths and weaknesses can be generalized for Bangladeshi organization and industries. There are few companies came with cloud facilities of their own. There are some others who are affiliating with cloud giants like Amazon, Google. they have no infrastructure of their own. Those who have their own cloud facility lacks the totality of cloud computing. they provide partial cloud facility only. they don’t meet all the requirements. most of the cases they have virtualization service with storage facility that can be accessed from anywhere. Important features like resource sharing and elasticity is not present there. some of them failed to achieve customer satisfaction like aamra technology’s ‘We cloud’. Largest private data center Colocity also coming soon with their cloud project ‘Megh-dut’, which promised to deliver something new. Bangladesh Government is planning to come with G-cloud when the National Data center in Kaliyakoir will be completed. That will be a huge step-forward for us in cloud-computing world. People will be get their facilities more easily then. Burden of official works will be less then. Main obstacles our private sector facing to implement a complete cloud computing facility is because of: - Security - privacy - Change in organizational structure - Performance - Financial - Legal - Learning - Sanctions - Lack of standards Beside that we have opportunity because of: - Cost efficiency - Service scalability - Efficiency in the use of IT - Business dimension - Faster-time to market - Innovation - IT development in small and medium size industries(SME’s) - Using cloud service in the development of e-learning and e-education - Using cloud service in order to develop and implement enterprise resource planning systems and customers’ relationships management - Using cloud computing service in order to realize e-government and e-voting - Using cloud computing in teleworking - Green Computing Conclusion Currently Cloud Computing is an emerging discipline that helps the IT industries to get efficient use of their Hardware and Software resources and enabling service-oriented, on-demand network access to rapidly scalable resources with promises to cut operational and capital cost. For developing countries like Bangladesh, cloud computing can be an appealing vision for cheap communications. But with advancement of cloud technologies and the increasing number of cloud users, data security dimensions are continuously increasing. So we think, the major problems of cloud need to be resolved and agreements must be made with service provider before major users will adopt clouds for sensitive data and computations.
