Why Cloud?

Technology Advantages of Cloudification

  • Mobility – Since cloud services are available over the internet, they can be easily accessed by customers from any device, at any time. Businesses also have the flexibility to shift operations from one place to another across geographies without any overheads and quickly
  • Scalability & Elasticity – Cloud provides operational agility for businesses to support the current and projected application loads. The capacity for each cloud service can be expanded and shrunk based on requirements
  • Reliability & Availability – Over the years, cloud infrastructure has become increasingly reliable. Based on the solution and business needs, cloud services can be further designed with the desired levels of availability
  • Performance – With auto scaling, data replication and traffic management, businesses can ensure that customers get the best possible performance, regardless of their location and application load
  • Security – Cloud providers have robust infrastructure and access to the best resources to ensure the safety of data. Multiple levels of physical and logical access controls ensure data access to only those customers with the appropriate permission
  • Disaster Recovery – Cloud infrastructure providers offer backup and recovery solutions as part of their standard service menu at a nominal charge
  • Manageability – Cloud solutions can be managed and maintained efficiently and effectively. Self-service portals enable businesses to manage the cloud solution without the intervention of the cloud service provider

Cloudification Benefits for your Business

  • Focus – The cloud enables you to focus on your core business and leave the mundane tasks of setup and maintenance to the cloud infrastructure provider
  • Choice – Once you’ve developed a cloud solution, you are offering your customers a choice of on-premise and cloud options. You can transition them to the cloud offering based on their needs and convenience. It allows you to maintain and grow your market share
  • Investment – After migrating all your customers to the cloud, you will experience the benefits of lower investment in development. The cloud solution can be designed for more frequent, incremental changes, without disruption. You don’t have to distribute software updates/patches. The cloud infrastructure provider also provides you cost-effective solutions for setup and maintenance
  • Pay-As-You-Go – You can pay as you go by designing the cloud solution to scale when your customers use it and shrink when utilization is low. You don’t have to make the huge upfront investment for future seasonal peak loads
  • Subscription – You can offer your customers subscription models, which makes it easier to configure different packages based on usage and functionality
  • Competitive Advantage – Due to low-cost access to scalable infrastructure, you can think big and innovate for increased competitive advantage

Cloudification Benefits for your Customers
