Let’s take a scenario of a Small business company having 5 users, opt for a physical on premises server solution, comprising of mailing office collaboration file server printing fax solution, NAS SAN or DAS for backup storage the hardware and software will cost Rs 3,00,000 INR USD 6000, this is a very conservative estimate A SMB class firewall with antispam will be needed to protect the mail server, the physical device will cost Rs 20,000 INR upward plus a annual subscription for updating the antispam database, A gateway AV solution Rs 2,000 INR, plus annual license subscription the mail server will need a dedicated IP (a logical no. that forms a network) cost depends on ISP. For an on call, break fix or regular maintenance support for the server will cost Rs 5000 to 8000 INR a month. Break down, down time technology obsolesce owners headache.
Cloud is available for Rs 2,500 INR or USD 50 per seat per month. No maintenance up time 99.9% else money back guaranteed. Protected from technology obsolesce, enterprise class Firewall antispam, gateway protection.
If any business person wants IT leverage, will definitely come to Cloud for a deal.
Cloud Computing How Secure?
Cloud offers platform as a service (NOS ), Infrastructure as a service (implemented on blade clusters virtualization like hyper V), Software as a service, be it word-processing to CRM to database, intergrated internal communication like IM video chat, mailing solution, collaboration software like Sharepoint, storage including backup sync to on premises NAS SAN or DAS infrastructure for business critical data. The cloud infrastructure has Enterprise class perimeter protection (Firewall anti spam) Gateway AV protection monitored 24X7 365 days.
- Point to point VPN (IPSEC encryption for data security) connectivity from cloud to business unit device.
- Edge protection, (on premises devices used in the organisation to access cloud) maintenance, surveillance, available at Rs 550 INR per device (Laptop desk top Mini Handheld etc).
How much of control do we have on our telephone / mobile operators switching system? Do we need? We want to make a call send an SMS or MMS, similar with cloud.
Cloud computing is a service.
Virtualization is a process, which converts physical hardware to logical (virtual), like partitioning of hard disk to logical C: D: etc, a crude example. This has huge benefit.
The physical server storage should have to be virtulazation ready by installing Hyper – v like software, virtualization is achieved.
