 Best For You Organics Company is one of the leading online health food suppliers in North America, serving customers in Canada, Mexico, and the United States. They launched their highly-successful e-commerce website, which sells subscriptions to their meal service, in 2016, and have been steadily increasing their subscriber-base since. Their service is tailored towards working professionals, who want convenient, reliable access to healthy meal choices, and pre-packaged recipes, without having to spend too much time preparing the meals. Customers can choose from a variety of meal plan options (vegetarian, vegan, gluten-free, high-protein, etc.), along with several options for portion sizes, and the number of meals per week. Meals are delivered weekly directly to the customer's home.
 
-Their CIO, Holly Franklin, is a big proponent of open-source software (OSS), and development of their web application was done using the MERN stack (MongoDB, Express.js, React.JS, Node.js). Their code is hosted in a private GitHub repository. A point of pride for Best For You Organics Company has been their developers' involvement in the open source community, with most members of the team frequently contributing to React.js on GitHub. They currently have a continuous integration workflow, triggered by each code check-in/commit in GitHub, using Jenkins.
+Their current meal plans include only dinner options, but Best For You Organics Company has received feedback from many customers expressing a desire that breakfast and lunch options be included as part of the service offering. They would like to expand their meal services to meet this demand, but feel they first need to address their rising infrastructure costs and management time. They have reached a point where managing their VM and server infrastructure is becoming a real challenge, and are interested in understanding more about Platform as a Service (PaaS) solutions for OSS applications that could help them focus their expenditures and efforts on their core business, rather than infrastructure. "We're finding that with every upgrade, we're spending more time and money on infrastructure, and less on delivering the functionality and features that matter most to our customers," says Holly Franklin, "and we need to rebalance those efforts." The development team at Best For You Organics has some experience with Docker, and is interested in what options might be available for using containers to deploy their application into a cloud environment.

     Web App for Containers was designing leveraging years of Microsoft's Azure App Service PaaS innovations, and allows developers to just focus on composing their containers without worrying about managing and maintaining an underlying container orchestrator. Container orchestration is obfuscated away from developers, and handled as part of the managed services.

+    By using Azure Web Apps in multiple North American regions, we can meet the high-availability needs of Best For You Organics Company. They could deploy Web Apps into several paired regions to ensure failover capabilities. In addition, this approach provides web front-ends close to current and future customers.
+
+    Configuring web apps to scale is simple using Azure App Services. A set of criteria is easy to define and then Azure will take care of the hard work to ensure that the web app is always responsive. This set of steps is easily completed by administrators based on a few different metrics, such as CPU, memory, etc.
+
+    Using an Azure CDN Standard or Premium from Verizon, we can pre-load files into nodes that are located closer to customers. This ensures that the load times for static content will be less than if they were served directly by the web application. All static content will be preloaded, including images and PDFs among other items on the site.

+3. What options does the customer have for a Docker image registry? What option you would recommend?
 
     The image registry is core to the CI/CD workflow, and must be a production worthy implementation, as it is the source of container images, versioning, deployment, upgrade, and rollback strategies. Registry images can also be used for cross-environment promotion (between development, test, staging, and production, for example).

     You can use your existing MongoDB expertise, application code, and tooling as Azure Cosmos DB implements the MongoDB 3.4 (version 5) wire protocol and supports the MongoDB aggregation pipeline. You can develop applications using MongoDB, and deploy them to production using the fully managed, and globally distributed Azure Cosmos DB service. In other words, your application only knows that it's connecting to a database using MongoDB APIs. It is transparent to the application that the data is stored in Azure Cosmos DB.
