Cloud Services and Computing
What is Cloud Services?
Cloud Services can help accelerate your cloud adoption, migration, management and operations of your cloud projects. The three types of cloud services that are traditionally provisioned and accessed from a cloud services provider are:
- Infrastructure as a Services (IaaS)
- Platform as a Services (PaaS)
- Software as a Services (SaaS)
By leveraging a cloud services provider, you can tap into their experience and capabilities to bring innovation to your business quickly.
What are the benefits of cloud computing?
Cloud is a mandatory benchmark for modern, competitive IT operations. By harnessing the power of the cloud, you can accelerate growth and deliver better experiences for your customers, digital workers, and IT developers. Here are the key benefits:
The cloud allows your organization to move more nimbly than competitors who may need to devote IT resources to managing infrastructure. Research has found that 77% of organizations feel that cloud computing gives them a competitive advantage. (HBR Report Cloud: Driving a Faster, More Connected Business).
Three Ways to Make your Cloud Adoption Strategy More Cost-Efficient
A cloud infrastructure scales on demand to support your fluctuating workloads, supporting the continuous growth of your organization. As your business evolves, the cloud accommodates your data growth requirements and grows with your needs.
Cloud computing uses remote resources, saving your organization the cost of installing and maintaining servers and other equipment. An on-demand delivery model can be leveraged allowing computing resources to be available to the users as needed. Cloud server providers continually optimize the hardware needs of their data centers, resulting in economies of scale.
Cloud-based services provide quick data recovery for emergency scenarios, from natural disasters to power outages. If hardware fails, you won’t lose your data because of networked backups.
The cloud offers businesses more flexibility compared to local hosting. And if you need extra bandwidth, with cloud you can meet that demand immediately, rather than undergoing a complex and expensive update to your IT infrastructure.
Cloud computing makes collaboration between organizations simple. Worldwide access means they can collaborate from all over the world and securely share information across a cloud-based platform.
What are the primary cloud deployment models?
The private cloud is the use of on-premises cloud computing resources by a single business or organization. A private cloud gives you greater visibility and control, as it is always maintained on a private network. The hardware and software are solely used by your organization.
Public cloud services are off-site and delivered over the public internet by a third-party provider. This can be a cost-effective and low-maintenance solution, as you don’t have to purchase, manage, and maintain the hardware and application infrastructure internally.
Hybrid cloud architectures always consist of at least one public cloud and at least one private cloud, but may also include on-premises legacy infrastructure. Often, touchpoints exist between the environments to create a unified, automated, and flexible computing environment.
Hybrid clouds make it easier to switch to a different style of cloud deployment and provide greater flexibility over the technology you use, allowing you to grow and innovate.
Multi-cloud is the use of multiple cloud and storage services in a single environment, which may be all-public, all-private, or a combination of both. Typically, a multi-cloud consists of two or more public clouds from different providers and often includes multiple private clouds. Each cloud tends to be dedicated to a single task. For example, you may run all networking activities in one cloud, while using database services from another. Multi-cloud provides flexibility and the advantage of drawing on the strengths of multiple cloud service providers.
How can you differentiate between hybrid cloud and multi-cloud models?
Components of a hybrid cloud typically work together, and always combine at least one public and private cloud. By comparison, a multi-cloud model typically uses at least two public clouds, and different clouds are used for different tasks.
What are cloud managed services?
Cloud managed services refer to another organization taking over the responsibility for maintaining and operating your cloud environment. These services may include a wide range of processes, functions, or applications, typically resulting in cost reduction and operational improvements while allowing you to leverage your own applications and processes.
Why should I modernize legacy applications to the cloud?
Application modernization is more complex than simply moving applications to the cloud. It requires a whole new digital mindset that emphasizes innovation, agile development, microservices, and automated deployment to achieve the best results for your organization. With application modernization, you can accelerate innovation and move towards your goal of digital transformation, no matter where you are in your transformation journey.
Why should I ensure the data in the cloud is secure?
If the data in your cloud contains information that is confidential or specific to your business, you want to protect it to only allow predefined individual(s) to access it. To secure you cloud, the most effective strategy is to adopt a continuous security assurance leveraging Cloud Security Posture Management (CSPM). A CSPM product ensures security and compliance amid the rapid changes within the cloud by pulling out actual cloud workload configurations and comparing them against defined security policies to identify deviations from the standard.
Incorporate CSPM principles and tools to comprehensively address cloud security and compliance and perform systematic security and compliance reviews across your hybrid and multi-cloud infrastructures, on-demand. This is part of security, risk and best practice guidance and detailed improvement plans, or, in many cases, security optimizations are automatically applied.
How does cloud security work?
Cloud security is the set of strategies, practices, and procedures that protect your data and applications hosted in the cloud. It differs from on-premises security models, so cloud-appropriate security and compliance must be established before cloud migration.
Security is closely entwined with everything in the cloud. Every component of the cloud has distinct security requirements—and each infrastructure component has its own unique security requirement.
In many cases, security is ‘flying blind’ when attempting to secure its expanding cloud. Lack of visibility and integration with security analytics tools are the main concerns cited by organizations in the industry.
Unifying security from on-premises to cloud and user endpoints through software-defined micro-segmentation may strengthen and simplify your current security posture. To succeed, cloud security and compliance require shared responsibility between the cloud vendor and the customer.
Cloud Security Posture Management Workflow from Design, Implementation to Operations
What is cloud shared responsibility model?
A shared responsibility model simply means that cloud provider is responsible for securing the cloud and as a customer you are responsible for securing the data and apps you put in the cloud.
The cloud provider should provide details of what security measures they provide, what security compliances they follow, and which elements fall to the customer or client.
What is cloud sprawl and shadow IT?
Shadow IT is the use of apps and services by employees, teams, or departments without the knowledge, oversight and, ultimately, control of your organization. Shadow IT in the form of SaaS applications is an ongoing, perpetual challenge for security professionals. The core problem is often unenforced security policies on an enterprise level. If system-wide best practices are established and enforced, the risk can be contained, dramatically reducing security vulnerabilities.
Cloud sprawl is the uncontrolled proliferation of your organization's cloud instances, services, or providers, oftentimes without your company's knowledge or oversight. Sprawl happens when organizations fail to properly monitor, manage, or control their cloud environment.

How do I ensure success in the cloud?
Our research shows that the level of an organization’s cloud success depends on how you adopt an advanced, core commitment to the cloud itself. You need to make the cloud a priority and set clear objectives. Otherwise, projects will fail.
Once you deployed your cloud, it requires a different set of tools and processes to effectively manage and operate.
Here is some guidance from our cloud gurus that you can take to optimize your cloud to make it more secure, less costly, and ultimately more valuable to your organization.
Right-size your CPU, storage, and memory, and closely manage your licensing and maintenance costs to make certain you’re using what you pay for—and no more. Managing multi-cloud environments with a single dashboard gives you more control and insight and could save you as much as 30%.
Harness the power of automation by looking for a cloud architecture that can dynamically address all aspects of performance as demands are placed on systems. Automation can scale resource capacity—both up and down—as usage varies, with little or no manual intervention.
Centralized performance monitoring allows you to keep a closer eye on performance, ensuring that all systems are running optimally.
Make sure you have an executable Disaster Recovery (DR) plan in place. Check that your cloud applications and processes are replicating to DR/HA (High Availability) sites as you expect, and that you have the right amount of storage. Don’t wait until a major outage to find out.
High availability sites consist of multiple ready-to-use systems, so if one fails, another can be seamlessly leveraged to maintain service availability.
Evaluate existing applications. Are they easy to use? Are they necessary, or have they become redundant over time? Are there apps you can eliminate, or can some be repurposed to achieve better results? Application Modernization tools can help you objectively assess current business processes and retool essential processes to save money and boost productivity.
