Understanding the Public Cloud: Benefits, Risks, and Cost Management

The Growth of Public Cloud Services

Public cloud computing represents a revolutionary shift in how organizations access and deploy IT resources. Defined as computing services provided by third-party vendors over the internet, public cloud has surged into a vibrant market. In fact, Gartner predicted a staggering market size nearing $400 billion in 2020. Two major segments dominate this landscape: Infrastructure as a Service (IaaS) and Software as a Service (SaaS).

Dominant Players in the Cloud Market

When it comes to IaaS, Amazon Web Services (AWS) leads the pack, closely followed by Microsoft Azure. On the SaaS side, the market is more diverse, featuring well-known applications such as Microsoft Office 365, Google G Suite, Salesforce, and Adobe Creative Cloud. These platforms have proven their worth by offering flexible solutions tailored for both businesses and individual users.

Key Benefits of Public Cloud

Organizations leveraging public cloud can tap into a multitude of benefits, leading to:

• Increased Agility: Quick access to a plethora of services allows for rapid experimentation and adaptation.
• Cost Efficiency: Reduced upfront investments and the shift towards operating expenses (opex) enable better financial management.
• Faster Time to Market: Organizations can deploy applications and services more swiftly than ever before.
• Technical Flexibility: Businesses can easily scale computing resources up or down based on demand.

Despite these advantages, it’s essential to recognize that public cloud also introduces new risks that businesses must navigate. IT asset management professionals are key players in cultivating strategies to mitigate these risks effectively.

Prioritizing Cost Management

Cost management emerges as a critical focus for businesses utilizing public cloud services. The nature of IaaS and SaaS makes it all too easy to overspend, emphasizing the need for meticulous tracking and understanding of resource utilization.

Organizations must ask:

• Who is using what resources?
• Where is the spending going?
• How can costs be controlled?

The Easy Accessibility of IaaS

One of the attractions of IaaS is its straightforward setup. Users can log into a portal and deploy virtual machines (VMs), build databases, and monitor IoT devices with minimal effort. However, this convenience comes with a catch. Unfettered access can lead to unchecked spending, ultimately impacting departmental budgets and organizational finances.

The On-Premise vs. Cloud Cost Paradigm

In traditional on-premise setups, companies invest in physical servers and software licenses, which incentivize increased usage to maximize ROI. Conversely, in the cloud, prolonged usage of idle virtual machines translates directly to wasted money. Cloud providers typically bill for resources simply ‘being on,’ rather than for actual usage.

Practical Cost Control Strategies

To illustrate, let’s consider a 31-day month with 744 billable hours. For many organizations, some cloud resources, particularly in development, can be turned off after hours or over weekends. Turning off VMs during non-working hours could save significant amounts of money.

Here are some additional strategies businesses can adopt to mitigate cloud costs:

1. Monitor Resource Over-Provisioning: Ensure appropriate sizing of VMs to avoid unnecessary expenses.
2. Evaluate Resource Utilization: Assess whether resources are actively being used and consider downsizing accordingly.
3. Review Payment Methods: While pay-as-you-go offers flexibility, reserved instances can provide major savings for long-term projects.

Navigating Public Cloud Governance

Effectively managing public cloud environments is more complex than it appears. Essential questions for governance include:

• What types of clouds are in use?
• What resources are being allocated?
• Who has permission to create resources?

Engaging stakeholders across the organization helps ensure that governance policies are well understood and adhered to.

Keeping Control of Cloud Environments

While traditional software asset management (SAM) tools may not fully accommodate the peculiarities of public cloud, organizations must consider investing in specialized cloud management tools. These can offer insights into cost management, automation, and security—facets critical for effective IT asset management.

Understanding SaaS Usage

A prominent issue faced by IT departments is the proliferation of SaaS applications. Organizations often underestimate their SaaS usage dramatically. This scalability grants employees the freedom to procure software independently, which complicates comprehensive management.

To tackle this challenge, organizations can pursue a multi-faceted discovery approach to gauge SaaS usage effectively. Often, limited visibility can mask potential compliance, regulatory, and security risks.

Optimizing SaaS Spending

With an accurate picture of SaaS usage, companies can begin the task of optimization. Like managing perpetual licenses, this process involves identifying substantial expenditures, understanding contract renewal timelines, and capitalizing on bulk purchasing power. The challenge lies in the vast number of suppliers now in play, making it crucial for organizations to remain organized.

Renewals and Unused Resources

With SaaS management tool suppliers reporting an average of 60 renewals per month for their clients, a renewals calendar becomes indispensable. Understanding metrics for renewal dates, contract terms, and notice periods allows businesses to strategize effectively.

Furthermore, awareness of the usage frequency of SaaS applications ensures that organizations can reclaim licenses for unused subscriptions swiftly.

Improving Compliance and Security

SaaS applications introduce unique compliance challenges. Organizations must develop robust tracking mechanisms to monitor data processing and security safety. Comprehensive analyses can reveal app permissions and their interactions with other applications, enabling IT teams to create a risk profile of their SaaS usage.

Enhancing the Employee Experience

It’s essential to recognize that the transition to SaaS isn’t merely a compliance hurdle; it also presents an opportunity. By analyzing which applications employees favor, IT can create a catalog of recommended tools that resonate with users, enhancing overall productivity and satisfaction.

Engagement from employees ensures that the shift to SaaS is seen as an enabler rather than a limitation. With the right strategies, organizations can leverage public cloud technologies not just for cost savings but as a transformative force to enhance productivity.

By addressing cloud utilization through thoughtful governance and cost management strategies, organizations can unlock the full potential of public cloud services while mitigating associated risks.
