Cloud Computing (CC) is an Internet-based form of application delivery, allowing business applications to be accessed without the hassle of managing network servers, operating systems, or storage capacity.
Accelerate time-to-value: By adopting the cloud, enterprise applications can be implemented rapidly instead of waiting months for IT teams to respond and purchase/install related hardware.
Cloud services provide businesses with significant cost, operational, and productivity advantages. Enterprise organizations may experience up to 109% ROI with a real-time value relevant to their organization size.
With a reliable cloud provider, IT teams can optimize applications and platforms to grow with the business – an impressive advantage over the traditional model of hardware purchases and infrastructure refreshes that often incur expensive and time-consuming updates.
Additionally, cloud-native environments accelerate innovation due to the agility provided by cloud computing. New versions can be deployed more rapidly throughout an enterprise instead of waiting until all users accessing it are updated at once, incurring risks with that strategy.
Cloud computing gives IT departments more freedom in managing, updating, and expanding services continuously, including integrating cloud-based services with existing apps. IT teams can use pay-as-you-go models for cloud services to adjust capacities and resources according to current demand and projected growth projections.
Location doesn’t matter with cloud data storage solutions. A reputable cloud provider allows your application to run securely from anywhere around the globe, lessening the IT department’s workload and freeing them up for other vital projects.
IT departments that utilize a reliable cloud provider can also boost security by moving to the cloud. This removes the need for on-premise hardware and provides more reliable backup and disaster recovery options, especially for smaller companies without access to expensive IT staff to support their hardware environments and IT environments. Furthermore, moving away from them mitigates cyberattack risks that more frequently target on-premise hardware and data.
Types of Cloud Services
Cloud services can be divided into three broad categories according to their deployment model: infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS). Users do not directly manage or control the underlying cloud infrastructure, including network servers, operating systems storage, or applications – they access these applications through a web browser or thin client interface as though they were locally installed on their device.
Companies that utilize Infrastructure-as-a-Service can take advantage of infrastructure resources they couldn’t build or manage themselves, saving on upfront expenses. Customers pay only for what they use and scale accordingly based on their needs. Plus, hardware and software maintenance are handled by service providers, while patches are regularly applied for security issues.
PaaS solutions enable company developers to focus on application development without worrying about infrastructure concerns. Instead, they can concentrate on business logic, functions, and applications while leaving server management tasks up to their provider in the cloud.
One of the primary advantages of cloud computing is easy remote access for work presentations, documents, or spreadsheets – this enables staff members to work from any device at any time, increasing productivity while improving collaboration. Coworkers can share documents instantly and anywhere across devices.
Reliance on the cloud, however, can have its disadvantages. For example, interruption to internet services will also impact business operations, while outages from cloud vendors have become increasingly frequent. While typically brief, they can have severe repercussions if backup systems are not implemented immediately afterward. Furthermore, vendor lock-in can cause significant problems when switching cloud providers later.
Security and Compliance
Organizations that transfer data to the cloud are subject to numerous compliance standards and regulations that could lead to fines, penalties, or other consequences for noncompliance – such as the Payment Card Industry Data Security Standard (PCI DSS) for merchants or Health Insurance Portability and Accountability Act (HIPAA) for healthcare entities.
Most cloud service providers employ multiple measures to protect data. These include installing network and application firewalls, virtual private networks, and other measures to keep cybercriminals away. Physical measures also include security doors, uninterrupted power supplies, CCTV monitoring cameras, air particle filtration systems, and fire protection, which help prevent direct access to hardware stored within data centers.
Cloud service providers encrypt data both during its transmission and storage. Encryption helps make the information less accessible to hackers or unauthorized users; however, if the encryption keys are compromised, the data could still be at risk. Tocompanies should implement strong password policies and sound critical management practices to avoid this happening again.
Cloud services also monitor data activity to detect misconfigurations or suspicious activity, providing organizations with tools that help maintain an orderly and compliant environment by alerting them of changes that violate policies. Some devices can compare current configurations to previous ones to show long-term compliance.
Cloud service providers must provide their customers with reports detailing compliance with various regulatory frameworks, typically including metrics such as log retention rates and privileged access policies and internal controls such as change management processes. Businesses must perform due diligence when reviewing these reports to find a cloud vendor that best matches their needs.
Organizations have implemented multi-cloud strategies to avoid vendor lock-in and take advantage of best-of-breed services that can be utilized independently. A multi-cloud strategy offers competitive pricing by choosing multiple cloud providers for different functions like data storage or CDN services.
Multi-cloud strategies may seem attractive, but they also present numerous challenges. Respondents to an IDG study identified controlling costs, data security, and governance as among the key issues. , Organizations must create an architecture and strategy based on business requirements and technology principles to navigate these obstacles.
Building a multi-cloud strategy begins with a thorough cloud assessment and planning process, which allows organizations to understand their current environments and the capabilities of each cloud provider so they can develop a roadmap to maximize infrastructure performance for the future.
This approach allows companies to leverage best-of-breed applications and cloud technology to increase employee productivity. For instance, employees can access their presentations and spreadsheets from any device connected to the internet – increasing productivity while decreasing travel and office space requirements.
Multi-cloud strategies offer another benefit – redundancy. Should a cloud app malfunction, its functionality can be quickly transferred from one environment to another without disrupting users. This can prevent significant downtime while protecting critical business operations from disruption.
Companies should carefully consider where their data should go when creating a multi-cloud strategy. While most cloud providers provide free ingress for data, egress charges often incur. This is important because some countries and industries require data residency requirements – telecommunications and manufacturing, for instance, have specific rules.
Lacking visibility into their cloud ecosystem, organizations struggle with transparency and mismanagement, resulting in increased costs. Businesses can gain visibility into their cloud environment by employing appropriate tools to maximize its benefits.
Cost management tools offer comprehensive and detailed reporting for an entire cloud infrastructure, including predictive analytics to forecast future expenditures. This helps businesses avoid unexpected cloud bills while allocating resources more efficiently; additionally, identifying unutilized or under-utilized resources allows companies to take advantage of discounts offered by cloud service providers.
Cloud expenses usually arise due to misallocating resources, particularly among large enterprises with multiple teams deploying code and using hardware. When this occurs, costs quickly add up, but reducing them becomes more straightforward with tools that track instances and allocate them specifically to teams.
By tracking usage data over time, these tools can detect when teams will require more hardware to accommodate growth or additional projects. They also help identify any anomalies or potential issues and alert groups so they can adjust their infrastructure appropriately.
Other features of these tools that make them worthwhile include their ability to power schedule and auto-shutdown instances when not in use, saving much money for long-running services. Furthermore, some allow users to run what-if analyses to evaluate potential outcomes of eliminating underused instances or adding reserved capacity – giving users insight into any impacts. Afterward, these instances can be swapped out for ones that provide similar functionality but at lower costs.
