This is according to Jai Menon, chief scientist at Cloudistics, speaking at ITWeb Cloud Summit 2019, held in Johannesburg today.
Discussing the future of cloud, Menon explained that as cloud services mature and a new generation of highly capable and easy-to-use private clouds emerge, we are seeing informed customers that are expecting to consume services from both private clouds as well as multiple public clouds.
"Every cloud vendor, including AWS [Amazon Web Services], has been forced to react to this new customer reality.
"The first two private cloud phases were cloud 1.0 (software-as a-service) which transformed the delivery of services. Then we saw cloud 2.0 (big data), which enabled the delivery and value of massive data sets," Menon pointed out.
"Now cloud 3.0 is emerging, which is all about delivering services in big compute. Until today, organisations had to manage their own infrastructure in some form or another, but cloud 3.0 ensures organisations don't have to worry about service patches and security patches. It enables increased usability and scalability, while providing an organisation with an application marketplace."
Detailing the cloud trajectory over the years, Menon explained that organisations have been slowly shifting from the use of virtual machines to container orchestration, which allows providers to deliver services in a fraction of the time.
"From container-as-a-service we're seeing a shift to monolithic application (a single-tiered software application), and then the next phase is the move from monolithic application to agile micro-services, which offer benefits in simplicity, speed, scale and flexibility. We will see a phenomenon where different teams will provide different agile micro-services which are offered together in applications."
Menon explained the three types of hybrid clouds which more organisations will be using in the next few years are: one-to-one hybrid cloud; one-to-many hybrid cloud and many-to-many hybrid cloud.
"One-to-one hybrid cloud is the portability between a specific private cloud and a specific public cloud. For example, from Azure Stack private cloud to the Azure public cloud.
"One-to-many hybrid cloud is the portability between a specific private cloud to more than one public cloud. Many-to-many hybrid cloud is when applications and data can be migrated among multiple, disparate private and public clouds."
So, organisations should think carefully about which cloud is better suited to their business structure, he advised.
