Consumers are changing the way they watch television \u2013 switching in record numbers to streaming channels instead of traditional cable or satellite services. The reason is simple: they are seeking a better viewing experience with more choice and the flexibility of paying only for what they use.\nThe same can be said for businesses and their search for a better IT experience. Today\u2019s traditional datacenters are struggling to keep up with the demands of the business. Many have turned to public cloud to move faster and increase flexibility. Yet, transitioning everything to the public cloud hasn\u2019t satisfied all their needs either \u2013 introducing cost, security, compliance, complexity, application latency, and data sovereignty issues.\nThis current debate of choosing between on-premises and off-premises IT distracts from the real issue of what organizations are trying to attain. The real IT trend I am seeing is the capability for organizations to run IT as a service (ITaaS), irrespective of where workloads are located.\nITaaS: A better IT experience\nAs organizations evaluate their best IT options, many understand that cloud is not a destination. Instead, it is a new way of doing business focused on speed, scalability, simplicity, and economics. Digitally transformed organizations are starting to move toward ITaaS because it provides them with more choices.\nEnterprise businesses demand a similar experience to the public cloud for all of their workloads \u2013 even those on premises. Businesses want IT delivered as a seamless consumption-based, fully-managed, on- and off-premises model.\nThis model continues to grow in popularity because it simplifies IT and frees up people and budget resources to focus on new initiatives and innovation. According to IDC FutureScape, 2019 predictions:\n\nBy 2020, consumption-based procurement in datacenters will have eclipsed traditional procurement through improved "as a service" models. (Worldwide Datacenter 2018 Predictions\u2014APEJ implications)\n\n\nBy 2022, the enterprises\u2019 need to optimize ROI, reduce budgets, and cope with the scarcity of cloud experts will drive spending on managed cloud services to nearly $75 billion and almost 25% of technology outsourcing. (Worldwide Cloud 2019 Predictions)\n\n\nBy 2024, 90% of Global 1000 organizations will have a multi-cloud management strategy that includes integrated tools across public and private clouds. (Worldwide Cloud 2019 Predictions)\n\nThese statistics point to a clear trend: enterprises will deploy a hybrid, multi-cloud IT strategy for all their workloads, and they will expect to consume everything as a service. ITaaS will become a reality for all workloads, both on-premises and off-premises, because it provides a better IT experience with the flexibility to get more at a lower cost. Simply put, businesses will move to ITaaS for the same reason customers are choosing new streaming internet TV channels over satellite and cable television services.\nWhat will it take for enterprise-class ITaaS to become a reality?\nIf this scenario sounds too good to be true, that\u2019s because the industry is moving in the direction of ITaaS, but it isn\u2019t quite there yet. Pieces of the ITaaS puzzle are starting to fall into place, but no one vendor currently has everything needed to provide a seamless experience. Hewlett Packard Enterprise (HPE) is working to solve many of the challenges associated with building a comprehensive ITaaS model.\nOne of the things you can do to get started with ITaaS is implement an on-premises infrastructure that ensures flexibility and cost-savings. Composable infrastructure is a good choice because it gives the enterprise more flexibility to scale compute, networking, and storage in a cost-effective way. Composability enables the enterprise to quickly compose and recompose infrastructure based on needs of each individual workload or application \u2013 IT simply dials in the type of resources needed from fluid resources pools, and then they easily manage it with software-defined intelligence.\nOn-demand ITaaS: A cloud-like experience on and off premises\nITaaS will grow in popularity because it gives enterprise businesses the flexibility to choose the different types of services they need when they need them. And best of all \u2013 it\u2019s simple to engage and cost-effective because businesses will only pay for what they use. On-demand ITaaS is coming soon to the enterprise, both on and off premises. And it\u2019s serving up a catalogue of IT products, tools, and technologies for a better IT experience with more flexibility in how it is consumed and paid for.\nThis article is the first in a series on ITaaS where I will share insights into this innovative trend.
