Top 10 cloud computing development trends in 2021

In recent years, cloud computing technology has developed rapidly. Industry experts predict that cloud computing will be more widely used in the next few years, and the global cloud computing market is also expected to reach a new high. In 2021, cloud computing will continue to be the basic goal of companies seeking to improve scalability, business continuity, and cost-effectiveness. This article shows the top ten cloud computing development trends in 2021.

The global public cloud infrastructure market will reach $120 billion

According to data from Forrester Research, the global public cloud infrastructure market will grow by 35% in 2021 to reach 120 billion U.S. dollars, and cloud computing will continue to "take a central position" in the recovery of the epidemic.

The research company said: "Before the outbreak, cloud computing was already in a rapid development stage, and it will reach a new peak by 2021, resulting in higher enterprise adoption rates, cloud revenues and business value."

By 2021, the global IT expenditure for cloud computing will continue to grow.

Gartner predicts that next year's global end-user spending on public clouds will increase by 18%, reaching 304.9 billion US dollars, higher than this year's 257.5 billion US dollars. Sid Nag, vice president of research at Gartner, said: "On-demand, scalable cloud brings cost-effectiveness and business continuity to enterprises, and provides impetus for enterprises to rapidly promote digital business transformation. The increase in the use of public cloud services makes cloud adoption a The'new normal'."

According to Gartner's data, SaaS will still have a relatively large share of the end-user cloud IT spending market, and is expected to grow by about 16% to reach 117.8 billion US dollars, while PaaS is expected to grow by 26.6% to about 55.5 billion US dollars. It is reported that the need for remote workers to access high-performance and scalable infrastructure through modern cloud-native applications has promoted the growth of PaaS. IaaS spending is expected to grow by 26.9%, reaching 65.3 billion US dollars.

The status of the three major cloud service providers changed

In 2021, the top three public cloud providers in the world will be reshuffled, and Alibaba Cloud will replace Google Cloud as the third largest in the global public cloud infrastructure market, second only to AWS and Microsoft.

Data shows that Alibaba Cloud's cloud computing revenue in the third quarter increased by 59% year-on-year to 2.19 billion US dollars, mainly from customer revenues in the Internet, finance, and retail industries.

Google Cloud's revenue (including revenue from Google Cloud Platform (GCP), Google Workspace (formerly known as G Suite) and other enterprise cloud services) increased from 2.38 billion US dollars in the same period last year to 3.44 billion US dollars.

Hyoun Park, CEO and chief analyst of Amalgam Insights, said: "Google Cloud has established a firm foothold in the ERP (Enterprise Resource Planning) field and is expected to achieve growth of more than 40% next year."

Amalgam predicts that AWS's revenue in 2021 will exceed the sum of the next three competitors, but AWS's revenue growth rate will be lower than the sum of Google Cloud and Microsoft Azure. "

This is good news for the industry, because it represents competition in the cloud market, not competition between Amazon and non-Amazon," Park said.

Park said that AWS will further promote the development of operation management services on the basis of communication, information and operational services (such as Amazon Chime, Amazon Simple Queue Service, AWS Chatbot and AWS RoboMaker).

At the same time, Park predicts that Microsoft Azure cloud computing revenue will exceed $25 billion in fiscal 2021, driven by the long-term needs of the cloud computing market and partners.

The edge is a new kind of cloud

According to Forrester's prediction, the edge is a new kind of cloud. "In 2021, we will see the emergence of new business models. These business models will promote the deployment of the edge. The development of cloud platforms, AI and 5G will also promote the use of edge use cases. Expand."

According to Forrester, large vendors including Dell, HPE, IBM, and Intel have joined the ranks of edge computing, launching cloud solutions that can be deployed anywhere. CDN and data center hosting providers also provide edge computing services in hundreds or thousands of local pop-ups. In the next three years, the buying interest of enterprises will shift from cloud computing to the edge.

Steve Miller Jones, vice president of edge strategy and solution architecture at Limelight Networks, said that the development of serverless computing and the creation of a distributed service layer around the cloud are driving the development of new real-time IT applications. Enterprises hope to bridge the gap between centralized cloud and end users through the network edge, so as to provide all users with low-latency application and content performance. Integrating distributed edges into cloud computing is the key to innovation in 2021.

Miller-Jones pointed out two key ways that the network edge will change and expand cloud computing. "By integrating the network edge into their cloud strategy, developers can easily deploy services at the edge without worrying about the additional operational overhead caused by increased infrastructure. Through integrated development and deployment pipelines, developers can integrate application services And functionality is moved from the cloud to the edge of the network. This will help create more responsive and dynamic applications."

As enterprises adopt distributed application environments, enterprise network edge security will receive further attention in 2021. Miller-Jones said: "The security of the entire network edge and the last mile is a key challenge faced by enterprises and will be achieved through security services at the network edge."

Artificial Intelligence Engine

Gartner stated in its "Top Strategic Technology Trends in 2021" report that companies need a powerful artificial intelligence (AI) engine strategy to ensure the success of their projects. Without an AI engine, most companies cannot push AI projects from proof of concept to mass production.

Considering maintainability, scalability and management issues, AI projects are often difficult to successfully land, but AI engine strategies can help improve the performance, scalability, interpretability, and reliability of AI models.

The AI engine makes AI a part of mainstream DevOps.

Gartner said: "The AI engine has three core pillars: DataOps, ModelOps, and DevOps. DevOps mainly deals with high-speed code changes, and AI projects will experience dynamic changes in code, models, and data, which must be improved. Organizations must be in DataOps data Only by applying DevOps principles between the pipeline and the machine learning (ML) model of MLOps can the advantage of the AI engine be obtained."

The beginning of multi-cloud and cloud joint provider services

2021 will be the beginning of multi-cloud and cloud joint provider services. Cloud vendors are gradually realizing that cooperation with each other will help accelerate the introduction of products and services to the market, make full use of each other's advantages, and challenge the dominance of AWS.

This idea is not so easy to accept at the beginning, because theoretically, the goal of the cloud platform is to become the only platform used by the company. However, with the development of the multi-cloud environment, the competitive landscape has changed, and cloud vendors must reconsider how they enter the market. The interconnection between Oracle and Microsoft in June 2019 is a good example. Oracle's network and Microsoft's machine learning capabilities can be used at the same time.

Microsoft and Oracle are competitors, but just last year, the two announced that they would connect their respective clouds to allow mutual customers to migrate and run enterprise application workloads across Microsoft Azure and Oracle Cloud. This move is to better compete with AWS.

The rise of serverless computing

Serverless is the next step in monolithic application architecture after service-oriented architecture and microservice architecture.

According to the "Flexera State of Cloud 2020" report, serverless is one of the five fastest growing PaaS cloud services in 2020.

At present, the industry has begun to use container and cloud-hosted general-purpose applications, and serverless is a boon for developers.

Up to now, a full understanding of AWS, Azure or GCP functions is a key requirement for cloud application developers. Looking to the future, this kind of detailed knowledge reserve will be solved by serverless, and the serverless interface in the cloud will become the interface for developers to interact with, rather than the underlying interface.

Automated cloud orchestration and optimization

As the number and quality of interconnected services across applications and services are very complex, cloud platforms will continue to develop automated cloud orchestration and optimization.

Park pointed out: "Automated service and performance management must become one of the most important aspects of choosing a cloud provider in 2021."

SASE adoption rate growth

The Gartner Hype Cycle curve shows that the Secure Access Service Edge (SASE) is at the peak of climbing and is currently being further adopted.

SASE is a network architecture that combines SD-WAN and cloud-native network security services (including zero-trust network access, secure web gateway, cloud access security proxy, and firewall).

With the increase of remote work, the pressure and limitations of virtual private networks are gradually exposed. Even if these problems are overcome or solved, they will still face bandwidth limitations, insufficient network segmentation, terminal security solutions vulnerabilities, and connection to the company. New problems such as untrusted devices of sensitive systems. SASE is a good alternative.

The "perfect storm" of data privacy and cloud migration

Balaji Ganesan, co-founder and CEO of Privacyera, a provider of data governance and security solutions, and co-founder of Apache Ranger, said that the growth of cloud infrastructure will create a "perfect storm" for data governance and compliance in 2021. .

Organizations need to ensure that data is safely migrated to the cloud, that is, before the IT or data team migrates data from on-premises to the cloud, all data required by the corporate data governance team is encrypted.

Ganesan believes that independent data security and governance tools will become an important part of mission-critical business processes. "By 2021, security, privacy and governance will be embedded in business processes."

Increased cloud management and cost control challenges

For many companies, shifting workloads to the cloud greatly improves the efficiency of operations and collaboration, but it turns out that the cost of doing so is also high.

Compared with traditional infrastructure, customers are still too immature in using cloud infrastructure skills, and they are still using them in an inefficient manner. Cloud waste hinders cloud adoption, operating efficiency is still very low, and customers cannot see the cost curve down.
