What Is Cloud Computing
Cloud computing and storage may seem like recent terms, but be aware that they are not that new.
That term was first cited in 1997 by Professor of Information Systems, Ramnath Chellappa.
In 2006, the first service in the segment to be widely publicized was launched by Amazon, which remains one of the main companies to distribute this type of functionality.
One of the things that scares users the most on whatever type of devices is the loss of important documents.
This is because the vast majority still depends on physical storage in the famous HD-
Which both in its internal and external version does not offer 100% security, since this is a very sensitive type of Hardware the most diverse variables, mainly to impacts.
With cloud storage – in English, Cloud, which is another name widely used for this type of service –
Where you use the server of a specialized company to store your commercial files or people (documents, photos, videos, music, among others.), this risk is almost zero.
These shared servers store data for thousands of people so that they can access it wherever they are and through any device – be it a notebook, tablet or cell phone –
This way, the user will not only depend on his computer, external hard drive or USB stick.
The location where these servers are located is called Data Centers, which in one location can store files from all over the world.
To clarify this concept, imagine a rental apartment building.
Cloud services work like this building, where each tenant rents their own space, with an infrastructure of water, electricity, telephone and gas that actually belongs to the owner of the building.
In this analogy, the building is like the cloud – or Data Center – and each room is a different company.
It is possible to visit one of Google’s Data Centers, which has one of the most popular cloud services, through its Google Street View tool.
What are the best cloud services?
The leading providers of cloud computing are companies known worldwide, with gigantic data centre infrastructures with physical servers spread across the globe.
We can classify cloud service providers into three distinct segments:
- Global cloud computing companies – Examples: Amazon, Microsoft and Google;
- Telecommunications companies – Examples: Telefônica, Oi and Embratel;
- Data Center specialist companies – Examples: Equinix, UOL and Matrix.
As there are no capacity limits for an application in the cloud, this has awakened in companies, which were never originally manufacturers of Hardware, the ability to offer elastic cloud offers, according to the needs of each client.
Below is a summary of the main cloud storage services from global companies specializing in that front?
Amazon Web Services
Amazon today is the absolute leader in cloud computing, primarily for businesses.
It offers several packages for the most varied processing needs of the market:
Databases, file storage servers, processing, video conversion/encoding, access control (Firewall), machine-learning, reports, data flow processing.
The list does not end here, and reaches over 35 different applications and offers, with solutions for small, medium and large companies.
There is also a service for individuals, Amazon Cloud, where for $ 59.99 a year it is possible to have unlimited space to store any file.
Google has long gone beyond search.
The company that, among many options, already offers free email accounts through Gmail, also has the Google Drive cloud service, which guarantees a 15GB account at no cost for home users, who, if they want to have more space, they can hire plans starting at $ 1.99 per month.
For companies, Google offers two different types of services:
A plan dedicated to professionals and teams who want to have access to Google Drive, Documents, Spreadsheets, Presentations, Forms and Hangouts,
All online and another that, in addition to these resources, it also offers Google Groups, Calendar, Sites and even personalized Gmail for the company.
In both situations, the value per user is the US $ 10 per month, including a free 30-day trial.
Storage is unlimited, except for teams with up to 5 people, who receive 1 TB of storage per user.
The Microsoft service is another option widely used by organizations.
Its advantage is that it can also be combined with the subscription to the Office package.
As in Google Drive, there are two options for plans, the first being R $ 21.90 / month entitling to 1TB per user and the second which costs R $ 43.70 / month with a capacity of 5TB per user.
In both alternatives, it is possible to synchronize the files on the PC, Mac, tablet and smartphone.
However, the second plan provides extra security features, such as advanced encryption and data loss prevention.
Home users are entitled to 5GB free, with the option of an upgrade to 50GB for just R $ 4.00.
Other famous names are also worth considering, such as Dropbox and iCloud – which is exclusive for users of Apple devices.
The Sendspace is another solution, suitable for fast action, as it allows up files in the cloud, creating a link that can be sent to download by third parties and that expires after a few days.
When to migrate to the cloud?
Many companies today are born without a single physical server of their own.
Everything is already stored in the cloud, in some global Data Center, being replicated in another physical location.
The advantage of this model is that it can invest in expansion as its demand also increases.
Other companies have decided to migrate some more common applications to the cloud, such as the email or web server, as these applications are the simplest to migrate.
Many Data Centers offer complete plans to migrate other company data, allowing users to start the next Monday on a new platform, with minimal impact on their productivity.
Applications such as telephony and call centre services are more complex and require more intense processing and should be migrated cautiously and monitored in the first few.
A tip is to talk to the manufacturer of the application used and if the application itself does not have a cloud structure.
If your company is starting, the options for storing and processing your data and applications in the cloud are the most sensible.
But if your company already has an IT team taking care of several servers internally, ask the following question:
How much will I save with hardware upgrades every two years?
And with a maintenance contract?
Downtime or even recovery time for broken equipment that had to be completely replaced?
In most cases, you will be surprised at the favourable outcome for migrating to the cloud.
Don’t be afraid not to have the equipment at your side.
Data is data. It just needs to be protected and backed up safely.
Virtual equipment is replaced in a matter of minutes, not days, like physical equipment.
It’s worth investing in the cloud!
