4 Cloud Computing Ideas that Have Faded Away

Cloud Computing

“Cloud computing is an exclusive model for setting a ubiquitous network access to a shared pool of configurable computing resources.”

The cloud is on its way to becoming the standard IT model. It integrates flexibility, scalability, and reliability into user-friendliness. It has developed some of the world’s largest companies like Microsoft, Amazon, etc., while empowering some of the SMBs as well. The cloud has advanced the economics of providing, utilizing, and promoting services, bringing new opportunities into a light—and a few teething problems too.

William Fellows is the vice president and co-founder of 451 Research, states that the value of the cloud including IaaS and PaaS is about $13 billion per year regarding revenue.

With the advent of cloud computing, many cloud technologies have morphed through developments, add-ons, and updates. Therefore, some of its ideas are not forgotten, they have just evolved.

Let’s get back to those ideas that are still the important part of cloud computing.

Cloud bursting

It is an application deployment model in which an application operates in a data centre or private cloud, and when the demand for computing spikes, it bursts into a public cloud. The benefit of a hybrid cloud deployment is that you only pay for additional computing resources when you need them. According to experts,“Businesses should use cloud bursting for increasing efficiency, non-critical applications that manage non-sensitive information.”

You can deploy an application locally, then burst to the cloud to cater all demands, or if you want to free up local resources for business-critical applications, then the public cloud is the place to move the application.

Cloud bursting is for those applications that are independent of a complex application delivery infrastructure or integration with other components, applications, and systems inherent to a data center.

Make sure you consider security and regulatory compliance requirements while considering cloud bursting. For instance, cloud bursting is a leveraging cloud solution for retailers, especially when they experience high demands during the holiday shopping season. Usually, cloud vendors do not provide a PCI-DSS- compliant environment, and retailer might put their data at risk by bursting it to the private cloud.

Various issues related to cloud bursting arise due to less availability of management tools and incompatibility among different environments. Virtualization vendors and cloud computing service providers have developed tools to shift workloads to the cloud and streamline hybrid environments, but usually, they want all environments on the same platform.

Cloud Abstraction

Integration capabilities and cloud abstraction are important to establish the hybrid cloud or multi-cloud environment that enables to access multiple cloud provider services in a unified manner, through a set of abstracted Cloud APIs.  Both cloud abstractions and integration offer a common deployment program that allows developers to use abstracted APIs and build Cloud-based applications and they don’t need to work with vendor-specific APIs.

Abstracted API  based applications get weakly connected to provider APIs, leading to swapping of cloud services without damaging the functionality of the business application. This insulates applications from service, SLA changes, and technology at provider’s end.

An important requirement of a cloud broker is its capability to integrate various cloud services of respective cloud providers into a service archive such that the collection of cloud services is summed up into an integrated grand service catalogue. This allows developing the hybrid cloud and a multi-cloud marketplace. The functionality of service aggregation is an important attribute of cloud brokers.

To learn more about a cloud, you can even take training like Azure training from experts to make the most of it.

Cloud failover

The hardest and one of the important things to do when building your cloud architecture is to remove all Single Point of Failures (SPoF). This means that all mission-critical services should be able to sustain a breakdown of any server. Netflix has taken this seriously and came up with a service called Chaos Monkey. The job of Chaos Monkey is to take down servers randomly. The idea is to force developers to design the code and architecture, keeping server failure issues in mind.

Though this is a great idea, most companies won’t have the resources to implement such a system.

Mostly, the first step for removing SPoFs is to implement failover IPs on important services. The level of complexity varies to perform this.  It is rather simple for something like a load balancer, but a lot difficult for other things like a database.

Traditional software vs software as a service

Traditional software

  • Users invest in the software upfront as a package and install it on the computers
  • Licences are limited to the number of users where users want to deploy the software

Software as a service

  • There are no upfront costs as users subscribe to the software monthly.
  • When there is no requirement, users can usually end their subscription.
  • All applications are updated, and data is stored in the cloud rather on individual computers.

Its benefits are:

NO HARDWARE COSTS

Because cloud provider supplies the processing power.

SCALABLE USAGE

No need to install new hardware and software. Additional storage can be accessed on demand.

INDEPENDENT OF LOCATION

Users are allowed to use applications from any location from any internet enabled device.

NO UPFRONT COSTS

No sooner a user subscribes, applications are ready to use.

AUTOMATED UPDATES

Updates are often free and deployed by the software provider automatically.

APPLICATIONS CAN BE CUSTOMISED

Applications are easy to alter to tailor the needs and branding of particular customers.

PAY FOR WHAT YOU USE

This is beneficial when services are required a specific period.

COMPATIBILITY

Any internet enabled device, such as desktops, smartphones and tablets give access to applications.
