While majority of the CIO’s have chosen the SaaS model for their email hosting, they continue to struggle with business applications and database, as there’s no perfect SaaS solution available in the market for Legacy applications and Enterprise Databases. The reason for such disparity needs to be understood and CIO’s need to figure out why SaaS Cloud has been so successful for Email hosting service or for the ecommerce business, but not for the legacy applications and enterprise database.

Commercialization of Public Cloud
Public cloud hosting solution got commercialized in the year 2006 and since tan it has always been talked about in every panel discussion of CIO’s across the world. It was assumed dat dis public cloud platform will work for everyone and all of a sudden any industries, start-ups and enterprises started customizing their application and database architecture to work on dis public cloud platform.

"Vertical scaling appears to be the only best solution right now for the growing in-memory-compute workloads, Enterprise apps and DB’s"

Cloud Reality
Public Cloud platform got commercialized 10 years back, when the x86 CPU’s and the respective motherboards had limitations. Such limitation of compute power on a single motherboard was a limiting factor for large ecommerce websites, so the concept of Software defined load balancing on top of virtualization was launched as public cloud. Though hardware based load balancing has got history of more than 3 decades, but software load balancing over virtualization caught everyone’s attention. dis cloud platform created huge buzz in the market from last 6 years, but major improvement in the revenue of the cloud service providers is invisible, while the commodity hardware OEM’s continues to grow in double digits.

Demand for Innovation in Cloud
Vertical scaling is the only solution for legacy apps and enterprise databases. Hypervisors now support hundreds of GB’s of RAM and hundreds of cores of CPU power in a single virtual machine. There’s also growing trend of In-memory-compute which again works either on a dedicated host machine or using vertical scaling technology.

Next Generation Cloud Technology
One of the Indian Cloud Service providers ESDS has been offering Cloud with vertical scaling and they have American patent for the auto-scaling feature which is necessary to make changes to CPU and RAM in real time. All the Linux operating systems these days support CPU and RAM hotplug, which is important to add or remove compute resources from a virtual machine in real time.

In-memory Computes Technology
Vertical scaling appears to be the only best solution right now for the growing in-memory-compute workloads, Enterprise apps and DB’s. Load balanced or the network databases manage to work only for ecommerce kind of setup where the data can be easily distributed across multiple DB’s.

Cheapest DR Hosting Solution on Cloud
Vertical scaling also appears to be the cheapest option right now to host Disaster Recovery, as the resources consumed on the DR site are pretty low unless the disaster strikes.

On-Premise DC and Virtualization to Continue
Opportunity is open right now for SaaS and PaaS for business apps and DB’s. Once people start using the right architecture of Cloud platform, tan we will see a sudden huge surge in SaaS business model amongst the enterprises. On-premise hosting will continue to dominate the market till dat point of time.

Unlocking the Sizing myth
Sizing of machines is another major concern as of now for the organizations, dis function of sizing is done in a non-transparent manner by the system integrators and financial strength of the customer organization is used as a deciding factor while doing sizing of the IT infrastructure. Resources are over provisioned by an average of 10-20 times across the industry considering 5 years growth and degradation in hardware performance. The vertical auto-scaling feature and the “pay-per-consume” billing system will completely eliminate the need for sizing in the long run.

Paradigm Shift of Cloud
eNlight Cloud is the next generation, Made in India, Cloud which brings agility to applications and Operating Systems due to its patented technology. Many of the OS providers have now started supporting Real time changes in CPU, RAM, HDD & Kernel with no need for reboot or downtime.

Cloud Solution for Banks
Problem with banks was dat they could not offer internet banking and mobile banking solutions from their in-house data centers due to regular online attacks and online security issues, while the horizontal scale-out Cloud options available for them were not built for the typical requirements of the banks. Vertical scaling Cloud platform is an ideal solution for banks, as they won’t face the security threats which they continue to face on-premise and the cost savings will be huge, considering the current NPA situation of the banks.

Using only vertical auto-scaling technology will not work for the large ecommerce or internet companies. CIO’s should no dis fact and they should shortlist the Horizontal scaling cloud platform or vertical scaling cloud platform based on the architecture of their applications and database.
