The benefits of cloud technologies have been proven for businesses of all sizes – from small companies to huge enterprises. The cloud helps business owners save time, effort and money by increasing their employees’ productivity. With all the benefits provided by cloud computing, business owners focus on what’s most important: growing their business. In order to benefit from the cloud maximally, users need to understand in depth how cloud computing works. Today we’ll discuss some common cloud misconceptions. Let’s dispel the popular cloud myths so that we can better understand the reality of the cloud.
1. The cloud is an innovation.
The idea of cloud computing is not as new as it seems to be: we just didn’t fully realize all the ways we’ve been using the cloud before the term “cloud computing” appeared. Using a mobile phone that doesn’t store data, basically means using the cloud. Another example is VOIP (Voice over Internet Protocol) which is also a cloud-based service. Facebook, Twitter, Gmail, online banking and bill payments, Google apps, Amazon.com are also examples of cloud-based software. So as you can see, we use cloud technologies every day, sometimes without even realizing it.
2. Cloud services are expensive.
The fact is small business owners who have chosen cloud technologies spend approximately 20% less on technology than those who don’t use the cloud. Implementing in-house technologies costs businesses a lot of money and effort. Cloud service providers solve all these problems, allowing business owners to concentrate on growing their business. There is no need to spend time and money on deploying and maintaining data servers.
3. The cloud is not reliable.
No system can guarantee 100% reliability, and neither does the cloud. However, cloud computing systems intend to provide a high level of redundancy and availability. The same level of reliability is possible to achieve in-house but it’s generally less cost efficient. Cloud technologies ensure a higher level of reliability and availability at a fraction of the cost.
4. The cloud is not safe.
Most cloud services employ a high level of protection by implementing a layered approach to security: starting with traditional firewalls and and sophisticated surveillance systems, additional protecting systems such as DDoS etc. Additional security can also be provided by encrypting data stored in the cloud. A cloud data storage service being hacked is a pretty rare occurrence. So why do we still not trust the cloud? The thing is that users can’t see the data servers physically, so they have an idea that the data might be insecure. That’s probably the reason why the myth that cloud servers are not secure still exists. But just because you can’t see it, it doesn’t mean it’s unsafe! However, it’s still important to review your cloud provider’s terms of service very thoroughly and be extra careful with confidential data.
5. Private clouds are secure by default.
Many businesses are implementing private clouds assuming that they’re secure just because they’re private. Another common misconception is that public cloud is insecure by default which is not true either. Security is not automatic: an appropriate security solution needs to be implemented into the cloud. There is no security (or insecurity) by default.
6. Public cloud providers access your data without your authorization.
Another big myth is that public cloud providers are selling users’ data to third parties or even using it for their own needs. They don’t. If you’re still in doubt, encrypt your data so that nobody can access it.
7. Performance is a problem in the cloud.
Performance actually depends on the types of clouds and use cases. In most cases, performance is higher in the cloud because the cloud provides a higher level of scalability and more available capacity. Sometimes (for example when running a database server), the level of performance may be less than a traditional server can provide. If performance is crucially important, consider a hybrid solution that lets you to synergize the scalability and cost efficiencies of the cloud and the performance of dedicated servers.
8. The cloud is difficult to integrate with my own applications.
Integrating service oriented applications is pretty simple. Non-service oriented apps require stronger and tighter integration: in this case hybrid solutions can come in handy since they’re designed to simplify the cloud integration process.
9. I should move everything to the cloud.
The cloud doesn’t always replace traditional hosting, sometimes it will rather complement it. Assuming that all types of apps are suitable for cloud computing is wrong. There are many situations when the cloud isn’t going to improve flexibility, performance and security, but instead using cloud-based solutions only makes things more complicated. In those cases implementing a hybrid solution can make sense: it combines the cloud and traditional hosting solutions. There can’t be pure cloud option for all types of applications. Just try to find a cloud provider who offers hosting options suitable for your application needs.
10. Virtualization and the cloud are the same thing.
Cloud computing involves much more than virtualization, virtualization alone does not make a cloud. However, it is a key technology that enables the cloud. Virtualization is basically focused on server and workload consolidation in order to reduce infrastructure costs.
