Technology Magazine takes a closer look into what is meant by the broadly used term ‘hybrid cloud’ and why it is so important.

What is it?

Simply put, a hybrid cloud is a mash-up of on-premises and off-premises IT resources.

To expand on that a bit, we can say that the hybrid cloud refers to a cloud environment made up of a mixture of on-premises private cloud resources combined with third-party public cloud resources that use some kind of orchestration between them. The advantage of the hybrid cloud model is that it allows workloads and data to move between private and public clouds in a flexible way as demands, needs, and costs change, giving businesses greater flexibility and more options for data deployment and use.

Hybrid cloud benefits:

  • Flexibility and scalability: Undoubtedly, the primary advantage of the hybrid cloud is its flexibility. It takes time and money to manage in-house IT infrastructure and adding capacity requires advance planning. The cloud is ready and able to provide IT resources whenever needed on short notice. The term cloud bursting refers to the on-demand and temporary use of the public cloud when demand exceeds resources available in the private cloud. For example, some businesses experience seasonal spikes that can put an extra burden on private clouds. These spikes can be taken up by a public cloud. Demand also can vary with geographic location, events, or other variables. The public cloud provides the elasticity to deal with these and other anticipated and unanticipated IT loads. The alternative would be fixed cost investments in on-premises IT resources that might not be efficiently utilized. For a data storage user, the on-premises private cloud storage provides, among other benefits, the highest speed access. For data that is not frequently accessed, or needed with the absolute lowest levels of latency, it makes sense for the organization to move it to a location that is secure, but less expensive. The data is still readily available, and the public cloud provides a better platform for sharing the data with specific clients, users, or with the general public.

  • Cost savings: The public cloud component of the hybrid cloud provides cost-effective IT resources without incurring capital expenses and labor costs. IT professionals can determine the best configuration, service provider, and location for each service, thereby cutting costs by matching the resource with the task best suited to it. Services can be easily scaled, redeployed, or reduced when necessary, saving costs through increased efficiency and avoiding unnecessary expenses.

Why hybrid cloud may not always be the right fit:

There are circumstances where the hybrid cloud might not be the best solution. Smaller organizations operating on a tight IT budget might best be served by a purely public cloud solution. The cost of setting up and running private servers is substantial.

An application that requires the highest possible speed might not be suitable for hybrid, depending on the specific cloud implementation. While latency does play a factor in data storage for some users, it is less of a factor for uploading and downloading data than it is for organizations using the hybrid cloud for computing. Because Backblaze recognized the importance of speed and low-latency for customers wishing to use computing on data stored in B2, we directly connected our data centers with those of our computing partners, ensuring that latency would not be an issue even for a hybrid cloud computing solution.

It is essential to have a good understanding of workloads and their essential characteristics in order to make the hybrid cloud work well for you. Each application needs to be examined for the right mix of private cloud, public cloud, and traditional IT resources that fit the particular workload in order to benefit most from a hybrid cloud architecture.

Should you go hybrid?

According to 451 Research, by 2019, 69% of companies will operate in hybrid cloud environments, and 60% of workloads will be running in some form of hosted cloud service (up from 45% in 2017). That indicates that the benefits of the hybrid cloud appeal to a broad range of companies. Clearly, depending on an organization’s needs, there are advantages to a hybrid solution. While it might have been possible to dismiss the hybrid cloud in the early days of the cloud as nothing more than a buzzword, that’s no longer true. The hybrid cloud has evolved beyond the marketing hype to offer real solutions for an increasingly complex and challenging IT environment.

If an organization approaches the hybrid cloud with sufficient planning and a structured approach, a hybrid cloud can deliver on-demand flexibility, empower legacy systems and applications with new capabilities, and become a catalyst for digital transformation. The result can be an elastic and responsive infrastructure that has the ability to quickly adapt to changing demands of the business.

As data management professionals increasingly recognize the advantages of the hybrid cloud, we can expect more and more of them to embrace it as an essential part of their IT strategy.

Legend: John McAfee

A controversial figure, John McAfee is credited with starting an entire technology industry around cybersecurity

John McAfee is credited with starting the entire cybersecurity industry. In 1987, he set up McAfee Associates and released VirusScan. Previous antivirus programs had been released, but McAfee’s was the first with mass appeal and was soon a day zero (or at least day one) installation for Windows users as well as corporate clients.

McAfee: divisive

But McAfee was also a hugely divisive character. He dismissed his own software, claimed he never used it, and rejoiced when Intel bought McAfee and took his name off “the worst software on the planet.” He was anti-tax, pro-drugs, anti-war and pro-free trade. He was also a tireless crusader for cyber awareness, and set up a political party called the Cyber Party in order to make a bid for the office of president of the US.

“I am now everlastingly grateful to Intel for freeing me from this terrible association with the worst software on the planet”

McAfee: born in the UK

McAfee was born in Gloucestershire, UK, but moved to Salem, Virginia, where his American father (his mother was English) shot himself when McAfee was 15. McAfee worked at NASA, Univac, Xerox, Computer Sciences Corporation, Booz Allen Hamilton and Lockheed. It was while working at the latter he was given a copy of Brain, the first computer virus for PC, and began to engineer a defence.

McAfee: controversy

Controversy dogged McAfee. He was implicated as a ‘person of interest’ in the search for a neighbour who had been shot. He married a prostitute. He claimed a cocaine baron was writing his biography. He was arrested for possession of an unlicensed weapon and for manufacturing drugs in Belize (later released without charge). There were various other arrests (mainly weapons related) but not much would stick until McAfee’s anti-tax stance caught up with him. 

McAfee: arrest

He fled the US as tax authorities turned up the heat on at least four years of non payment of tax and was arrested (again) in Spain in October 2020 at the behest of the US Department of Justice. Charges for fraudulently promoting cryptocurrencies were soon added and he was formally indicted in March 2021. In June 2021, the Spanish National Court authorised McAfee’s extradition to the US, and McAfee was found dead in his cell just hours later in what is widely believed to be a suicide.

McAfee: death

Even in death, McAfee courted controversy, having announced that if he was ever found to have committed suicide, it would mean he had been murdered. A slew of conspiracy theories mushroomed in the hours after his death was announced. It’s just what he would have wanted.
