Cloud Computing challenges associated with it

Cloud Computing challenges

Cloud  computing  is  a  set  of  IT  services  that  are  provided  to  a  customer  over  a  network  on  a leased basis  and  with  the ability to  scale  up or  down  their  service requirements. Usually cloud computing  services  are  delivered  by  a  third  party  provider  who  owns  the  infrastructure.  It advantages  to  mention  but  a  few  include  scalability,  resilience,  flexibility,  efficiency  and outsourcing non-core  activities.  Cloud computing offers an innovative business model for organizations to  adopt  IT  services  without  upfront  investment.  Despite the potential gains achieved  from  the  cloud  computing,  the  organizations  are  slow  in  accepting  it  due  to  security issues and challenges associated with it. Security is one of the major issues which hamper the growth of cloud.

Businesses across industries have come to a consensus about the inherent business value of cloud computing and are increasingly transitioning to the cloud. Cloud’s popularity has grown immensely, as more and more recognize its benefits of improving data access, freeing up internal IT resources for more strategic tasks, cutting costs, and increasing flexibility, versatility, efficiency and economies of scale. However, the ongoing development and growth of cloud and its vast benefits are limited by Cloud Computing challenges and inconsistencies that exist in its current state.

Concerns about the data security and the efficiency and effectiveness of cloud services are a result of these Cloud Computing challenges.

  1. Data Protection

Data Security is a crucial element that warrants scrutiny. Enterprises are reluctant to buy an assurance of business data security from vendors. They fear losing data to competition and the data confidentiality of consumers. In many instances, the actual storage location is not disclosed, adding onto the security concerns of enterprises.

In the existing models, firewalls across data centers (owned by enterprises) protect this sensitive information. In the cloud model, Service providers are responsible for maintaining data security and enterprises would have to rely on them.

  1. Data Recovery and Availability

All business applications have Service level agreements that are stringently followed.
Operational teams play a key role in management of service level agreements and runtime governance of applications. In production environments, operational teams support

  • Appropriate clustering and Fail over
  • Data Replication
  • System monitoring (Transactions monitoring, logs monitoring and others)
  • Maintenance (Runtime Governance)
  • Disaster recovery Capacity and performance management

If, any of the above mentioned services is under-served by a cloud provider, the damage & impact could be severe.

  1. Management Capabilities

Despite there being multiple cloud providers, the management of platform and infrastructure is still in its infancy. Features like “Auto-scaling” for example, are a crucial requirement for many enterprises. There is huge potential to improve on the scalability and load balancing features provided today.

  1. Regulatory and Compliance Restrictions

In some of the European countries, Government regulations do not allow customer’s personal information and other sensitive information to be physically located outside the state or country. In order to meet such requirements, cloud providers need to setup a data center or a storage site exclusively within the country to comply with regulations. Having such an infrastructure may not always be feasible and is a big challenge for cloud providers.

  1. Security

It  is  clear  that  the  security  issue  has  played  the  most  important  role  in  hindering Cloud  computing  acceptance.  Without doubt, putting your data, running your software on someone  else’s  hard  disk  using  someone  else’s  CPU  appears  daunting  to  many.  Well-known security issues such as data loss, phishing, botnet (running remotely on a collection of machines) pose serious threats to organization’s data and software. Moreover, the multi-tenancy model and the pooled computing resources in cloud computing has introduced new security challenges that require novel techniques to tackle with. For example, hackers can use Cloud to organize botnet as Cloud often provides more reliable infrastructure services at a relatively cheaper price for them to start an attack.

  1. Limited Control

Since the cloud infrastructure is entirely owned, managed and monitored by the service provider, it transfers minimal control over to the customer. The customer can only control and manage the applications, data and services operated on top of that, not the backend infrastructure itself.

Though I have covered a few Cloud Computing challenges but there may be more depending on the ever changing requirements of the organisation. These seems to be challenges in today’s environment but with the ever increasing adaptability this is the future.
