When the famous poet William Wordsworth wrote I wandered lonely as a cloud, That floats on high o’er vales and hills he might have never imagined even in his wildest dreams that cloud might one day refer to computers, information technology (IT) and software applications access through a network/internet connection.
Cloud is a vast network of remote servers around the globe which are hooked together and meant to operate as a single ecosystem. IT resources, services, storage, backup, software program applications or an entire infrastructure can live in the cloud.
Why is it that more organizations are shifting to the cloud?
Cloud computing is a big shift from traditional business methods, in cost and IT resource balancing.
Advantages of cloud which are influencing organizations to move over to cloud computing are easy scalability, control, centralized security mechanisms, reduced network latency for applications and greater economies of scale as well as real-time monitoring. These include but are not limited to
- Cost cutting as the capital expense of computing resources, hardware, software, installation and on-site applications can be avoided by utilizing from the cloud as required.
- Speedy self services available on demand providing businesses flexibility. Resource unavailability crisis does not occur and capacity planning is not affected.
- Scalability is a major advantage of cloud computing. You can scale up or down as needed – be it with IT resources, computing power, storage, bandwidth, etc; irrespective of geographic location technology or time zones.
- Protect data cost-efficiently through latest policies, technologies and controls. This is done by secure transfer over the Internet to cloud storage systems that have secure access and data protection from potential threats.
- Performance upgrades with advanced computing hardware, network, applications and infrastructure, which are periodically upgraded to the latest.
- Create new apps and services by swift builds which can be deployed anytime across required platforms.
- Ease of storage, back up and retrieval of data and anytime-anywhere accessibility from any device, etc.
How Does Cloud Storage Work?
Cloud storage works through the internet. It allows users to access, work remotely, upload – download data on laptops, tablets or smart phones. You can have software running on your own hardware, software, applications, resources, APIs, etc on the cloud as required.
Depending on specific needs, prices vary for cloud storage. As an individual user, you can usually get initial amounts of cloud storage for free – such as 5GB included in iphones or ipads with iCloud.
Which are the different types of Clouds and the services available?
The different types of clouds are
- Public cloud – owned and operated by a third-party where all the hardware, software and supporting infrastructure is owned and managed by the cloud provider.
- Private cloud – cloud computing resources are available for exclusive used and are maintained on a private network. Third-party service providers also host private clouds.
- Hybrid cloud – combination of public and private clouds so that data and applications transfer between private and public clouds is easy.
The different types of cloud services are
- IaaS – infrastructure as a service
- PaaS – platform as a service
- SaaS – software as a service
