Mastering Cloud Development using Microsoft Azure

Chapter 2. Enhancing the Hybrid Process

In this chapter, you will learn how to integrate services to their local environment and processes. By integrating their local environment with the cloud, companies implement hybrid solutions to help themselves improve efficiency.

CloudMakers.XYZ

CloudMakers needs to manage some old software solutions already developed before this cloud experience. The migration in the cloud should be transparent, because there is not a specific activity for the customer. They need to recreate the same deployment environment for three-tier web applications to minimize the impact of the migration.

A frontend web server and a backend relational database make up the infrastructure for a typical three-tier, data-centric application. It was a common solution back in the last decade (and in some cases, a common solution today). This is due to some facts, which are mentioned here:

  • The lack of affordable and performing alternatives to a relational database brought us to the typical "database-first" approach, best supported by tools that "scaffold" the database and automatically build the pages for CRUD operations.
  • There was no culture for scalability, as all invocations were synchronous. So, one of the main topics was the...

Service Manager (classic) mode versus Resource Manager mode

Azure has introduced Azure Resource Manager (ARM) to solve the challenges related to the way we manage projects in Azure. Most of the solutions deployed are a combination of two or more services. For example, running a virtual machine requires the deployment of three different services:

  • A VM instance
  • A storage account that contains the disk images
  • A cloud service

A customer solution is more complex that this, and there are two main issues:

  • Deploying a solution can be complex due to the number of services that needs to be created and configured
  • Organizing and managing all these resources can become cumbersome if we cannot associate some metadata to describe why we have deployed every single resource and the solution it refers. If we can do this, we can then list, group, and filter services by solution and have a more clear and usable view of resources

ARM has changed the way we manage and deploy resources by including the following features...

Configuring a Resource mode Virtual Network for the frontend servers

A VN is a representation of your own network in the cloud. It is a way to organize your VM. Three important aspects that need to be considered are:

  • Resource management: Group and subdivide VMs in different VNs by internal security policies (some VMs cannot reach some others VMs).
  • Address spaces: Different virtual networks can have different sets of addresses. A single address space can be subdivided into subnets.
  • Security: While internal to a single VN, each VM can reach other VMs by default. You can control inbound and outbound traffic at subnet-level VMs with Network Security Groups.

VNs in an Azure account can be found in the Ibiza portal in two distinct containers by going to Browse | Virtual Networks or Browse | Virtual Networks (Classic). From the Classic portal, you will find only Classic VNs.

You can create a VN by going to New | Networking | Virtual Network, by deciding whether you need a classic or a Resource Manager...

Configuring a Service mode (classic) Virtual Network for the backend servers

At the time of writing this book, not all virtual network features have been migrated to ARM virtual networks. VPN is one of these features. Therefore, it is necessary to create a VN in the Service Manager mode to configure a VPN to have safe access from the CloudMakers office. As we have two VNs, it is also necessary to have a safe and privileged access from the frontline ARM VN to this backend VN.

Configuring VN in the classic mode is quite different from ARM. The configuration in the service is XML-based (not JSON-based, like ARM), and it has no specific API. You need to write some XML to configure your VN. One issue is that you can change or create your VN only at the account level. There is only one network configuration XML that contains the network configuration of the entire account. Making changes to this configuration for a project can affect your other deployments.

Tip

Connecting two virtual networks with site-to-site connection

We have created a Service Mode Classic VPN named CloudMakersClassic in order to access to VPNs. We have created another VPN in an ARM Virtual Network called CloudMakers to take advantage of the resource templates and resource groups. The two virtual networks are different by features and by roles, one being the VN for frontend servers and one for backend servers. Up to now, they don't communicate with each other. Up to now, they are two unrelated networks that could communicate only with public IP (but in our sample only ARM VN has one) and without any special privilege. In this situation we can have some security issues, that we need to avoid. So, we can configure a site-to-site connection to allow a privileged access to the classic VN. So, we can configure a site-to-site connection to allow access to the classic VN.

To start, we need to configure CloudMakers' ARM VN, the frontend ARM VN, or, in VPN terms, the local...

Configuring Office connectivity with a point-to-site VPN

To connect to the VPN from Office, a point-to-site VPN connection is necessary. From the virtual network configuration, create a new VPN connection, selecting the type as Point-to-site:

Configuring Office connectivity with a point-to-site VPN

Client Address Spaces is the client network assigned to the user's virtual adapter when they connect to the VPN.

The authorization in a point-to-site VPN is certificate-based. It is an asymmetric encryption algorithm that is used to sign the communication, where the keys are contained in certificates. A self-signed public key certificate means that the trust to the certificate is given by the fact that it was received by the VPN via an upload from an Azure account by the owner of the Azure subscription.

To create a self-signed certificate for a Windows developer with Visual Studio 2015, Makecert.exe is the tool necessary to generate it. In the Developer Command Prompt for Visual Studio 2015, type the following command:

makecert -sky exchange -r ...

The work is focused and provided a general overview. The book promotes the service however excludes general examples of applications and performances. In general, the text is worth reading, however, the text might need supplementation for successful application of the Azure Cloud Platform.

Ich bin vom Buch sehr enttäuscht.Ich habe es gekauft mit der Hoffnung, dass es mir schnell einen Überblick über MS Azure und den Programmieraspekten diesbezüglich verschafft. Obwohl das Buch eher dünn ist, es es voller Theorie und ziemlich langatmig geschrieben. Ich hatte Schwierigkeiten konzentriert zu bleiben. Ausserdem hat es mir nicht einen Überblick verschafft.Jetzt nach nicht mal 70 Seiten habe ich keine Lust mehr, es weiterzulesen. Stattdessen schaue ich mich nach einem anderem Buch um, dass sich etwas "glatter" liest.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
