DESCRIPTION
Here's what most people already know about cloud: It's cheaper than owning tons of servers. You can scale up or down as per your business needs. And you don't have to worry about upgrades, patches and so on. As for security – the world's divided on that! But is that all you should know? In this webinar, our speaker walks you through some of the things you must know about cloud. As your business grows, what are the things you must keep in mind? Are the costs linear? How secure is it? Can you ensure business continuity, cost effectively? Can you migrate to a different service provider easily? Learn insightful facts about cloud for business through this webinar video: http://goo.gl/JmM2G5

The cloud’s great, but it’s still evolving. So there’s lots still to know
What you already know
The Cloud
Marks the shift from
You owning hardware and software and running it to
You buying a service running on them, or you renting them for
your business needs
Pay as you go
Scalable, elastic
But security issues exist. But it’s the future!
Now let’s talk of stuff that most people don’t know about…
1. All clouds are not equal
That’s why pricing of cloud vary so much
You can build clouds out of commodity hardware and ‘not-yet mature’ software. You might want to question before running your ERP on it.
You can build clouds out of hardware and software that’s tried, tested, benchmarked, secure, is backed up by technical experts
You can find private clouds in state-of-the-art setups or in dingy basements
Be aware of your business needs.
2. All clouds are not managed
You would expect the team you bought compute or storage from to run it like clockwork, alert you about downtime or performance bottlenecks, and work proactively to keep your business going
Most clouds are NOT managed. There is no proactive monitoring necessarily unless you pay for it and management is definitely something you should look for before you sign. Sometimes you pay 4-5 times of that low-cost server you signed for.
Does someone do your backups as per schedules, are they managed, are you alerted when they fail?
What’s in the SLA? Check before you sign up.
3. Not as transparent as you think
It looks cheap, but is it really? Per hour costing tends to make it look cheap.
Specifically look at your storage requirements especially when you have a lot of IOPs needs (databases, large # of
transactions) and you may need to sign up for expensive storage (and that may be very different from what you thought it to be initially!!)
Get a clear picture of your needs, and how they will grow. And ask how much it will cost over time.
4. Is it secure? Likely to be more secure than most businesses running their
own show in-house.
But even so, threats are increasing manifold on a daily basis
Enterprise-class security systems must be in place.
Ask for what is installed, who has access, how is access given? Certifications, practices, security architecture, ask about the
kind of vulnerabilities that have happened in the past.
Ask your Cloud Service Provider if Security (for example, Firewall, Intrusion Prevention Systems) services are included or not and what is that you need to pay for, or is it DIY?
5. Clouds will be increasingly local
More businesses will move their clouds applications and hosting to their own countries
Drivers - Privacy, Government Regulations, Latency
Remember Snowden?
6. Availability is loosely defined
Jargon of Tier 2, 3 and 4
99.9982 (1.6 hrs of downtime per year) – this is Tier 3
Cloud service providers have to deal with many challenges (not just power, networks, etc but also OEM patches, incompatibilities, etc)
How do you know what you signed up for? And what are you actually getting?
If any down-time is something that can kill your business, set up services across different data centers and/or clouds
7. Support: All talk, no show?
Is there a number you can call? Is there a human answering your call?
Is there someone solving your problem so that the application doesn’t go down? Or that downtime is averted?
You have compute, storage, security, VPN, OS, infrastructure. You have applications on Windows, Unix and Linux.
Who is responsible for support and maintenance?
Is there a Single Point of Responsibility?
8. Can I change my CSP/XSP?
When you sign up for a cloud service, it usually means that you have signed up for as long as your business application is operational What if you don’t like the service? Or your company merges
with another and you have to migrate the applications?
Yes, but it can be a breeze or sometimes a lengthy and cumbersome process. Common standards are still emerging.
9. Careful about licensing
Pay attention to the licensing models, especially with Microsoft.
Does you service provider allow licensing mobility?
Remember – the cloud is rapidly evolving, please check again if you need to, for what held true a few months/weeks ago
may not be true anymore
10. It’s a delivery model, not a tech
Yes it has evolved out of technologies such as grid computing, utility computing and SaaS (remember ASP?)
It’s a paradigm shift in how IT is delivered and consumed
And it ensures better, more optimal use of IT resources
Great opportunity or threat depending upon how you use it or respond to it
11. Cloud’s not new!
As a concept, it’s about 40 years old!
Resource pooling (time sharing), measured service, and rapid elasticity...old concepts!
What has changed – Internet connectivity – availability, reliability; Mobility, WWW
