What is an Azure App?
An Azure app is not a monolithic product but rather a broad term for any application built, deployed, and run using the services and infrastructure of Microsoft Azure’s cloud computing platform. These applications are designed to leverage the inherent benefits of the cloud: scalability, high availability, global reach, and a rich ecosystem of managed services. Instead of being hosted on a single, on-premises server, an Azure app lives within a dynamic environment that can adapt to changing demands, from serving a handful of users to millions.
At its core, an Azure app can be a powerful cloud application for web and mobile, a set of highly-available and infinitely-scalable cloud APIs, or a complete full-stack web application. The platform supports various architectural patterns, allowing for the deployment of containerized applications, the development of modern apps using serverless containers, and the construction of complex systems based on microservices.
The defining characteristic of an Azure app is its integration with the Azure ecosystem. This allows developers to build scalable, high-performance applications from scratch or modernize existing ones, such as legacy SQL Server applications. By utilizing managed and intelligent SQL databases, developers can create applications that scale seamlessly. This means you can build everything from a simple web front end to always-on, scalable, distributed applications that are resilient and performant under any load. The essence of an Azure app is its ability to utilize a vast toolbox of cloud services to deliver functionality that would be immensely complex and expensive to build and maintain in-house.
Reasons It Is Difficult to Develop an Azure App In-House
While the potential of Azure is immense, the journey of in-house development is often challenging. Many organizations underestimate the paradigm shift required to effectively build and operate in the cloud, leading to common and costly mistakes.
Overwhelm and Foundational Neglect
One of the first hurdles customers face is being overwhelmed by the sheer number of possibilities within Azure. With hundreds of services, it is common to struggle with understanding how to even begin the journey. This initial excitement about building a new application can cause a critical error: teams often shift their entire focus toward the application or workload itself, neglecting the foundational elements that ensure long-term success. Core components like logging, monitoring, alerting, and security become afterthoughts. This neglect makes operating, maintaining, and troubleshooting the application significantly harder down the line. A strong foundation is not a luxury; it is a prerequisite for a stable and manageable cloud environment.
Operational and Documentation Deficiencies
There is a profound difference between merely deploying an application to the cloud and successfully running and operating it over time. In-house teams often lack the experience to establish well-documented, replicable patterns for consumers of the cloud environment. Without readily available documentation and clear, repeatable processes, each new deployment or update becomes a bespoke effort, increasing the risk of errors and inconsistencies. This lack of operational maturity means teams cannot respond to changes, including system failures, in a timely and effective fashion.
The “Bill-Shock” Phenomenon
Perhaps the most jarring challenge for companies new to Azure is the dreaded “bill-shock.” After running their environment for a month or two, they are often surprised by an unexpectedly high bill. This financial strain typically stems from a failure to adopt cloud-native cost management strategies. For example, teams often do not think about shutting down Virtual Machines during off-hours to avoid unnecessary spending. They may also fail to right-size their workloads, such as choosing the correct App Service Plans, database SKUs, or storage tiers, resulting in paying for over-provisioned resources. The ability to automatically scale out (or up) and in (or down) in relation to demand is another powerful cost-control feature that is frequently overlooked. Furthermore, many companies let valuable free MSDN credits for development environments go to waste, missing a key opportunity for savings.
The Automation and Mobile Integration Imperative
Automation still does not seem to be high on people’s lists when planning a cloud environment, yet its absence is a significant drag on productivity. Without automation, teams are perpetually busy with “unimportant,” repetitive tasks, pulling them away from value-added work. The cloud also necessitates a mental shift where infrastructure is treated as code—a concept previously associated only with software developers. This “infrastructure as code” approach is almost non-negotiable for modern cloud operations, and teams without this skillset will struggle.
These challenges are magnified when integrating Azure services with mobile applications. As one user, SBadger, discovered when trying to access Azure resources from a smartphone, mobile integration can introduce unique issues. SBadger encountered a “network problem” on an Android device using a cross-browser, even when health diagnostics showed no issues. This highlights that ensuring seamless access and performance across different mobile devices, browsers, and network conditions is a specialized skill. This is precisely where we at MetaCTO excel. As experts in custom mobile app development, we understand the critical layer connecting your powerful Azure backend to the user’s mobile device. We bridge the gap, ensuring that the integration is robust, secure, and provides a flawless user experience, no matter the platform.

Cost Estimate for Developing an Azure App
Understanding the cost of an Azure application is crucial, but it’s not always straightforward. Pricing is flexible and depends heavily on the services used, the chosen pricing model, and usage patterns. It’s important to remember that prices are estimates; the actual cost can vary based on your agreement with Microsoft, the date of purchase, and currency exchange rates.
Core Pricing Models
Azure offers several ways to pay for its services, allowing you to optimize for your specific budget and commitment level.
- Pay-as-you-go: This is the most flexible model. You pay for App Service compute capacity by the second, with no long-term commitments or upfront payments. It’s ideal for applications with unpredictable traffic or for development and testing.
- Azure Savings Plan: For predictable workloads, you can commit to spending a fixed hourly amount on select compute services for a 1- or 3-year term. This unlocks lower prices on those services until your hourly commitment is reached.
- Reservations: This model provides a significant discount over pay-as-you-go prices. You purchase a one-year or three-year agreement to use a specific instance of a service, effectively reserving that capacity at a lower rate.
App Service Plan Tiers
The primary cost for many Azure apps comes from the App Service Plan, which defines the compute resources your application runs on. Except for the Free tier, an App Service plan carries a charge for these resources. Here is a breakdown of the common tiers.
Free and Shared Plans
These plans are metered per app and are suitable for development, testing, or very low-traffic applications.
Plan | CPU | RAM | Storage | Pricing |
---|
F1 Free | 60 minutes/day | 1 GB | 1 GB | Free |
D1 Shared | 240 minutes/day | 1 GB | 1 GB | Free per site |
Basic Service Plans
These dedicated compute tiers are designed for apps with lower traffic requirements that still need features like custom domains and SSL. Additional savings like plans and reserved instances are not available for this tier.
Plan | Cores | RAM | Storage |
---|
B1 | 1 | 1.75 GB | 10 GB |
B2 | 2 | 3.50 GB | 10 GB |
B3 | 4 | 7 GB | 10 GB |
Premium v3 Service Plans
These plans are for production applications and offer a wide range of compute power. They are eligible for all pricing models (Pay as you go, Savings Plans, and Reserved Instances).
Plan | vCPU | RAM | Storage |
---|
P0v3 | 1 | 4 GB | 250 GB |
P1v3 | 2 | 8 GB | 250 GB |
P1mv3 | 2 | 16 GB | 250 GB |
P2v3 | 4 | 16 GB | 250 GB |
P2mv3 | 4 | 32 GB | 250 GB |
P3v3 | 8 | 32 GB | 250 GB |
P3mv3 | 8 | 64 GB | 250 GB |
P4mv3 | 16 | 128 GB | 250 GB |
P5mv3 | 32 | 256 GB | 250 GB |
Isolated v2 Service Plans
These plans run in a private, dedicated App Service Environment, providing maximum security and isolation for mission-critical applications. They incur a flat “Stamp Fee” for the environment itself, plus a charge for each isolated worker instance.
Plan | Cores | RAM | Storage |
---|
I1v2 | 2 | 8 GB | 1 TB |
I2v2 | 4 | 16 GB | 1 TB |
I3v2 | 8 | 32 GB | 1 TB |
I4v2 | 16 | 64 GB | 1 TB |
I5v2 | 32 | 128 GB | 1 TB |
I6v2 | 64 | 256 GB | 1 TB |
Additional Costs and Billing Nuances
Beyond compute, several other services contribute to the total cost.
- SSL Certificates: While App Service Managed Certificates are free (one per custom domain, standard only), you may need to purchase more robust options. A Standard SSL Certificate costs $69.99/year, and a Wildcard SSL Certificate is $299.99/year. SNI-based SSL is free to use, but IP-based SSL costs $39/month per certificate.
- SQL Database: App Service offerings include a free 20MB SQL database for the first 12 months. After that period, it converts to a paid basic SQL subscription if you choose to continue using it.
- Billing for Stopped Apps: A critical point to remember is that you are charged for apps in a stopped state. The charge is for the reserved compute resources in your App Service Plan. To avoid these charges, you must delete the apps or downgrade their plan to the Free tier.
- Billing by Tier: In the Shared tier, each app is charged for its CPU quota. In dedicated tiers (Basic, Standard, Premium, Isolated), you are charged for each VM instance in the plan, regardless of how many apps are running on it.
Visual Studio subscribers can benefit from a Dev/Test offer, which provides savings of up to 55% on several App Service plans.
