Over the past decade, the cloud has been an integral component of software development and overall business operations. It has opened various possibilities for small and medium-sized businesses as well as individual users to gain easy access to data storage and processing capabilities. From powering video streaming, web-based apps, customer relationship management (CRM) systems, mobile banking, inventory, and big data analyses, the cloud is helping empower businesses of all sizes to focus on innovation rather than infrastructure. What are the services in the cloud and what should you know about cloud security?
Cloud computing refers to storing and accessing data, software, programs, or services over the internet — the cloud — instead of in physical hard drives, servers, or mainframes.
Through cloud computing, important data can be accessed at any time with internet connectivity, regardless of where the user is located. It also allows organizations the flexibility to allocate and reallocate resources based on their dynamic needs.
Cloud providers such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud, provide computing resources to users and organizations all over the world.
The cloud has paved the way for organizations across industries to undergo digital transformation. And the shift has been swift — according to Forbes, by 2020, a staggering 83% of enterprise workloads will already be in the cloud.
The business advantages of cloud computing
Because organizations are freed of the burden and responsibility of maintaining and paying for their own infrastructure, the time it takes to develop and deploy applications and services is drastically reduced. Organizations can focus on application development rather than the laborious manual upkeep and maintenance of infrastructure to ensure that software and tools are on the latest versions.
Through the cloud, organizations become more streamlined — therefore, they are able to reach their customers faster, test and deploy their applications quicker, and drive innovation further.
On-demand self-service. Users can automatically arrange for cloud computing resources according to their needs and demands, without needing to communicate first with their cloud service provider.
Broad network access. With internet connectivity, users can access user-friendly and cloud-dependent capabilities over any platform — whether via mobile phone, a laptop, or a workstation — anywhere in the world.
Resource pooling. Cloud is a multitenant platform. This means that multiple users can use a cloud service and be provided with the number of resources that they require, without being able to regulate or know exactly where the resources are located.
Rapid elasticity. At any given time, users can acquire more or fewer cloud resources as they scale up or down, corresponding to the business’s demand. Companies can quickly upgrade or downgrade storage options or move from one as-a-service choice to another without needing to make a substantial change to its current IT infrastructure.
Measured service. To supply an increasing demand, cloud service providers are able to provide enough resources to users that require more in order to continue its service. Because of its being highly measured, users’ usage or consumption levels are accurately observed, controlled, and detailed for both users and providers.
A Closer Look at the Cloud
What are the different cloud computing deployment models?
An infrastructure that is open for use by the general public or a large industry group
Operates on a multitenant model; multiple users from different organizations access the service at the same time
The cloud service provider has ownership and provides maintenance and management of the cloud service
On-demand capability allows resources to be allocated dynamically based on users' requirements
Exists on the premises of the cloud service provider and can be accessed via the internet
Usually used for less-integral applications or operations
Ideal for single users and small and medium-sized businesses
A dedicated infrastructure that services a single organization and is inaccessible to those outside of the organization
Operates on a single-tenant model; only an organization’s employees can access the private cloud for different operational needs
The organization is responsible for paying for the acquisition, deployment, and maintenance costs
Resources can be allocated dynamically based on users' demands
May exist on the premises of the cloud service provider or as server configurations physically running on the organization's premises
Usually used for sensitive data or applications, as well as operations that require a high level of control
Ideal for healthcare organizations, government agencies, financial institutions, and telecommunication companies
A combination of both public and private cloud models, pairing the dependable nature of the private cloud and the on-demand capacity of the public cloud
Ideal for businesses that provide services or offer products
What are the different cloud service models?
Software as a Service (SaaS)
SaaS is the most widely used type of cloud service model. Applications are hosted by a cloud-based service provider and can be accessed over a network or via the internet. Simply put, it's using an essential software that’s not saved on a computer, but instead, on a server that can be accessed via the internet.
From 2015 to 2018, there has been a 155% increase in worldwide market growth for SaaS. It is estimated that by 2022, the market will be worth US$143.7 billion — a whopping 358% increase from 2015’s numbers.
SaaS providers manage, maintain, and have control over the cloud infrastructure (both hardware and software) as well as its security. SaaS examples include Gmail or Office 365, Google Apps, Salesforce, and Netflix. Because of its user-friendly nature, SaaS does not require technical skills to use or adopt.
New releases and automatic updates
Low upfront costs
High usage rates
Platform as a Service (PaaS)
PaaS is a cloud computing model where users or organizations can create, test, manage, and host their applications. It provides users with computing resources as well as tools and software to develop their apps, including middleware, database management, or the operating system. Like SaaS providers, PaaS providers manage, maintain, or have control over the cloud infrastructure as well as its security.
PaaS is mostly used by application developers and, hence, requires technical skills to operate.
Public cloud PaaS market revenue is estimated to grow to US$47.8 billion by 2026 — a whopping 2,887.5% increase from 2016’s combined revenue of US$1.6 billion.
Reduced administration costs
Centralized and simplified application management
Faster time to market
Infrastructure as a Service (IaaS)
IaaS is a cloud service model that provides users or organizations computing and processing resources, virtual machines (VMs), storage, as well as networks. Its servers may include physical as well as virtual ones. Unlike SaaS and PaaS, IaaS users have control over the cloud infrastructure as well as its security. The IaaS service provider takes care of the infrastructure while the user buys, installs, and manages the operating systems, middleware, and tools they need to develop their apps.
Highly technical professionals like infrastructure and network architects use IaaS.
Small and medium-sized businesses in North America spend US$9,500 on IaaS per year.
Reduced startup and maintenance expenses
More rapid innovation
Enhanced business continuity and disaster recovery
