Cloud Computing – not so old, not so new but still staggered a lot of people around the world on daily basis. The question is: What is it? Why we need it? What security does it offer? How much it cost? It’s uptime availability? What to choose – Public or Private Cloud? Lots of questions to make you confused. Small or big as well as new or old – almost every individual or business, looking out for an option that provides better security, cost saving, privacy and a lot more.
Here are the five points that helps you understand all about Cloud Computing:
The term cloud computing refers to the delivery of scalable IT resources over the Internet, or in simple words, it helps you perform tasks which would traditionally have been performed through the hardware (computer, servers etc.) located within your office, now via Internet. It can offer you resources-rich atmosphere, which can include applications and services, along with the infrastructure on which it operates.
4. PRIVATE VS. PUBLIC CLOUD
Cloud computing distinguished as under two different categories, it would be private cloud or it would be a public cloud. A private cloud refers to the centralized hardware and software within a company, keeping your all information in-house and not risking in putting data into a third party’s hand. Whereas, in a public cloud means typically involving renting out space in a shared data center, it would be a boon for small businesses but for larger companies having tons of data, it is bit risky in terms of privacy.
Amazon, Rackspace, Google are among those to name the few on which the current cloud ecosystem built providing world-class data centers. The best part among them is these cloud providers consider security as the backbone of their state-of-the-art infrastructures. There data centers on which cloud-based hosting take place keep an extra note on cutting edge encryption as well as on security tools, including advanced intrusion, zero-day threat detection. Along with this, these companies are having strong physical security all around their data centers, which includes video surveillance, perimeter fencing, security guards and a lot more.
2. COST EFFECTIVE
When you plan to use cloud-based service, it will costs you on subscription basis i.e. all you need is to purchase a subscription for the service you want to opt for as per your requirement and choice. Many providers offer free pilots also, with an approach when these free pilots turn into paid services automatically. Setup costs are also another area to look into. What you can relief about is security comes under the same subscription model, so you can get some relief over on this.
1. BENEFITS AND DRAWBACKS
Cloud Computing results in reducing hardware maintenance costs, ease of sharing data and applications and automated backup while the biggest drawback is that your whole – 100 percent – system relies upon your internet connection.
