The advantages of cloud computing are numerous. Learn how the cloud benefits organizations large and small.
- [Narrator] Once you understand the ideas behind Cloud Services, I think the next question to ask is what are the benefits of moving to the Cloud. Cloud computing eliminates the capital expense of buying hardware and software. This saves you money. Once the hardware is gone, it frees up time for your team members to work on other tasks. Gone are the hours managing racks of servers. Plus, you stop managing the infrastructure. No more hardware setup or running on-site data centers. Also, you don't directly pay the electric utilities for power and cooling.
Sure that cost are part of your subscription, but they tend to be lower than what you'd pay to your local utility. You pay only for the compute power, storage and other resources you use, with no long-term contracts or upfront commitments. For example, I have a virtual machine that I use for teaching some of my courses. I turn it on before recording a segment, and turn it off when I'm done. I get a bill for a few cents at the end of the month. The biggest Cloud Computing Services run on a worldwide network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient Computing Hardware.
This offers several benefits over a single corporate data center, including reduced network latency for applications and greater economies of scale. The beauty of Cloud Computing is that the servers are off-premise, out of sight, and out of your control. Suppliers take care of them for you and roll out regular software updates including security updates. So you don't have to worry about wasting time maintaining the system yourself. Most Cloud Vendors have availability service agreements, stating the system will be available 99.9% of the time, you're paying for rock-solid up time.
When there is an issue, say that Cloud Vendor Backbone goes offline and effects service, you get automatic professional troubleshooting. All the Cloud Vendors, have contingency plans for failures, have redundant resources available to be activated in a crisis. This is important for any organization, but especially for small businesses without the staff or deep IT knowledge to handle down time. Security is important, especially when you decide to entrust other vendors to manage your resources.
All Cloud providers offer a broad set of policies, technologies, and controls that strengthen your security posture. Your data, apps, and infrastructure, will be well guarded from potential threats. Their data center is going to have better Access Control than your suburban office space. Plus, lost laptops are a billion dollar business problem. Losing the hardware is expensive. Losing sensitive data on the laptop drive, is worse. Because your data is stored in the cloud, you can access it no matter what happens to your machine.
Another benefit is scalability, which means that your resources can seamlessly increase or decrease in size or quantity. For a startup, this could mean having one database server to start with, and adding servers when the business grows. Elasticity is a similar benefit that is related to scalability. It is the ability to grow or shrink infrastructure resources dynamically as needed, based on demand. Scalability gives you the ability to increase or decrease your resources, and elasticity, lets those operations happen automatically according to configured rules.
In a sense, Cloud Computing resources appear to be infinite or automatically available. The web is international, so Cloud Services need to adapt to global issues. A good Cloud provider has data centers located strategically around the world, so that latency times are low for network access. Also regions are important for compliance reasons. There might be legal constraints on where data can be located. For example, it must be geo-located within the European region. The advantages of cloud computing are numerous.
Cloud adoption is on the rise every year. There's a reason over 85% of enterprises have implemented a multi-cloud strategy in recent years. Over time, the infrastructure will only get better, which will translate into increased benefits for all of us.
