6. Pricing

Datadog and AppDynamics employ different pricing structures for their services, each with advantages and potential drawbacks.

  • Datadog: Datadog adopts a usage-based pricing model, charging customers based on their consumption. This approach can make Datadog a more affordable option for organizations that only want to pay for the resources they use. However, as usage increases and more features such as detailed logging and custom metrics monitoring are added, costs can escalate quickly. This can be a concern for organizations with growing monitoring needs, as it may lead to unexpectedly high bills.
  • AppDynamics: AppDynamics utilizes a subscription-based pricing structure with monthly fees based on the number of CPU cores monitored. This means organizations pay a fixed monthly or annual fee for access to the platform's capabilities, regardless of actual usage. While this provides predictability and stability in pricing, it can lead to over- or under-provisioning of resources. Depending on the organization's usage patterns, this can result in unnecessary costs or insufficient resources.

When choosing between the two platforms, consider your organization's usage patterns, budget, and the features you require. Datadog's usage-based model may suit businesses with fluctuating needs or those that want to keep a closer eye on costs. AppDynamics' subscription-based model offers cost stability and may be preferable for organizations seeking predictability in their budgeting.

Lucidity: Comprehensive Solution for Automated Storage Provisioning

While AppDynamics and Datadog provide complete observability and insight into storage metrics, such as as over or under-provisioned resources, they  have drawbacks. Implementing these tools across the cloud architecture to monitor resource utilization can be expensive and time-consuming, requiring the monitoring of numerous instances. 

This is where Lucidity enters. It offers an excellent solution for understanding and addressing the issues uncovered by these tools. 

As a leading cloud cost optimization tool, Lucidity specializes in helping companies minimize their block storage expenses. Several Fortune 500 firms, including American Airlines and SpartanNash, rely on Lucidity to significantly reduce cloud spending.

But why is there a need to have a separate tool for storage? 

A report by Virtana highlights that storage is a major contributor to the overall cloud bill. In the report, 94% of the 350 IT personnel surveyed stated their cloud costs were increasing alarmingly, with 54% confirming that their storage expenditure was growing faster than their overall cloud bill. 

Despite such numbers, many organizations neglect storage optimization. This may be due to:

  • The time-consuming and resource-intensive nature of custom tool development
  • Limited capabilities provided by CSP platforms, which often hinder storage optimization tasks
  • Lack of real-time shrinkage and expansion capabilities

Moreover, over/under-provisioning leads to resource inefficiencies and insignificant cloud bills. Therefore, addressing these hidden cloud costs through automated scaling of storage resources is essential. 

Lucidity enables you to address issues that arise when teams handle storage using traditional approaches:

  • Downtime: Sudden workload increases can cause downtime, forcing DevOps teams to work harder. Businesses may also overlook activating monitoring agents or setting alarms, leading to delayed responses. Lucidity's smooth storage shrinkage and expansion occur without impacting performance.  
  • Disk Wastage: Lucidity helps you quickly identify idle, unutilized, and overprovisioned disk space, allowing you to understand how to eliminate it. 
  • Overall Spend on the Disk: Lucidity provides insights into your disk spend and optimized bill, helping you save up to 70% on storage costs. 

The core offerings of Lucidity- storage audit and block storage auto-scaler- enables you to optimize your cloud costs seamlessly and without downtime. These solutions integrate effortlessly with your existing cloud infrastructure.Unlike manual operations, which can be labor-intensive, time-consuming, and prone to downtime, Lucidity's NoOps solution eliminates these challenges and significantly reduces the workload for DevOps teams.
