Inbound and outbound

Inbound firewall rules define the traffic allowed to the server on which ports and from which sources. If no inbound rules are configured, no incoming traffic is permitted.
Inbound rules: These are to do with other things accessing your computer. If you are running a Web Server on your computer then you will have to tell the Firewall that outsiders are allowed to connect to it.
Inbound means someone else from outside of your computer initiate the connection to your computer, so the traffic starts flowing inward to your machine
Inbound rules filter traffic passing from the network to the local computer based on the filtering conditions specified in the rule.

Outbound firewall rules define the traffic allowed to leave the server on which ports and to which destinations. If no outbound rules are configured, no outbound traffic is permitted.
Outbound rules: These are so that you can let some programs use the Internet, and Block others.
Outbound means you initiate the connection and the traffic starts flowing outward of your computer to the destination you intended. Example you connect to a server.
Conversely, outbound rules filter traffic passing from the local computer to the network based on the filtering conditions specified in the rule.

1 Concepts

High Availability (HA)
The ability of the application to continue running in a healthy state, without significant downtime. By “healthy state,” we mean the application is responsive, and users can connect to the application and interact with it.

Increase or decrease the resources and services used based on the demand or workload at any given time. Vertical Scaling (aka “scaling up) – add more resources to existing servers. Horizontal Scaling (aka “scaling out) – add more servers.

Vertical Scaling (aka “scaling up”)
The process of adding resources to increase the power of an existing server (e.g. adding a faster CPU, additional CPUs, more memory).

Horizontal Scaling (aka “scaling out”)
The process of adding more servers that function together as one unit (e.g. adding more servers).

Automatically add or remove resources based on demand.

Cloud Agility
Cloud agility is the ability to rapidly change an IT infrastructure in order to adapt to the evolving needs of the business (e.g. if your service peaks one month, you can scale to demand and pay a larger bill for the month. If the following month the demand drops, you can reduce the used resources and be charged less).

Fault Tolerance
Redundancy is often built into cloud services architecture so if one component fails, a backup component takes its place. This is referred to as fault tolerance and it ensures that your customers aren’t impacted when an unexpected accident occurs.

Disaster Recovery
The ability to recover from rare but major incidents: non-transient, wide-scale failures, such as service disruption that affects an entire region. Disaster recovery includes data backup and archiving, and may include manual intervention, such as restoring a database from backup.

Economies of Scale
Economies of scale is the ability to do things more efficiently or at a lower-cost per unit when operating at a larger scale (e.g. the ability to acquire hardware at a lower cost than if a single user or smaller business were purchasing it, cloud providers can also make deals with local governments and utilities to get tax savings, lower pricing on power, cooling, and high-speed network connectivity between sites).

Capital Expenditure (CapEx)
CapEx is the spending of money on physical infrastructure up front, and then deducting that expense from your tax bill over time. CapEx is an upfront cost, which has a value that reduces over time.

Operational Expenditure (OpEx)
OpEx is spending money on services or products now and being billed for them now. You can deduct this expense from your tax bill in the same year. There is no upfront cost, you pay for a service or product as you use it.

Infrastructure-as-a-Service (IaaS) (shared responsibility model)
Infrastructure as a Service is the most flexible category of cloud services. It aims to give you complete control over the hardware that runs your application (IT infrastructure servers and virtual machines (VMs), storage, networks, and operating systems). Instead of buying hardware, with IaaS, you rent it. It’s an instant computing infrastructure, provisioned and managed over the internet.

Platform-as-a-Service (PaaS)
PaaS provides an environment for building, testing, and deploying software applications. The goal of PaaS is to help you create an application quickly without managing the underlying infrastructure. For example, when deploying a web application using PaaS, you don’t have to install an operating system, web server, or even system updates. PaaS is a complete development and deployment environment in the cloud.

Software-as-a-Service (SaaS)
SaaS is software that is centrally hosted and managed for the end customer. It is usually based on an architecture where one version of the application is used for all customers, and licensed through a monthly or annual subscription. Office 365, Skype, and Dynamics CRM Online are perfect examples of SaaS software.



Purchase, installation, configuration, and management of their own software operating systems, middleware, and applications.

Cloud provider

Responsible for ensuring that the underlying cloud infrastructure (such as virtual machines, storage, and networking) is



Responsible for the development of their own applications.

Cloud provider

Responsible for operating system management, and network and service configuration.



Users just use the application software; they are not responsible for any maintenance or management of that software.

Cloud Provider

The cloud provider is responsible for the provision, management, and maintenance of the application software.

Public Cloud (most common)
This is the most common deployment model. In this case, you have no local hardware to manage or keep up-to-date – everything runs on your cloud provider’s hardware.

Private Cloud (2nd most common)
In a private cloud, you create a cloud environment in your own datacenter and provide self-service access to compute resources to users in your organization.

Hybrid Cloud (stepping stone to cloud, segmenting work, cloud bursting)
A hybrid cloud combines public and private clouds, allowing you to run your applications in the most appropriate location.

Benefits of Cloud Computing
• Cost Effective: Pay-as-you-go, consumption-based pricing model. Rather than paying for hardware up-front, you rent hardware and pay for the resources that you use.
• Scalable: Increase or decrease the resources and services used based on the demand or workload at any given time.
• Elastic: Automatically add or remove resources based on demand.
• Current: Computer hardware and software is automatically maintained by the cloud provider.
• Reliable: Cloud providers offer data backup, disaster recovery, and data replication services. Redundancy is often built into cloud services architecture so if one component fails, a backup component takes its place.
• Global: Cloud providers have fully-redundant datacenters located in various regions all over the globe (performance, redundancy, compliance).
• Secure: Cloud providers offer a broad set of policies, technologies, controls, and expert technical skills that can provide better security than most organizations can otherwise achieve.

2 Core services

Geography (Americas, Europe, Asia Pacific, Middle East and Africa)
An Azure geography is a discrete market typically containing two or more regions that preserve data residency and compliance boundaries.

Region (e.g. North Europe, West Europe, Germany North, Germany West Central)
A region is a geographical area on the planet containing at least one, but potentially multiple datacenters that are nearby and networked together with a low-latency network.

Availability Zone (e.g. Zone 1, Zone 2, Zone 3 – within a particular region)
Availability Zones are physically separate datacenters within an Azure region. Each Availability Zone is made up of one or more datacenters equipped with independent power, cooling, and networking.

Availability Sets
Availability Sets comprise of update and fault domains. Update Domain: When a maintenance event occurs, the update is sequenced through update domains. Fault Domain: Fault domains provide for the physical separation of a workload across different hardware in the datacenter.

Hierarchy: Geography > Region > Availability Zone > Availability Set > Fault Domain/Update Domain

Region Pair
Each Azure region is always paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away. This approach allows for the replication of resources (such as virtual machine storage) across a geography that helps reduce the likelihood of interruptions due to events such as natural disasters, civil unrest, power outages, or physical network outages affecting both regions at once.

The Azure DDoS Protection service protects your Azure applications by scrubbing traffic at the Azure network edge before it can impact your service’s availability. Within a few minutes of attack detection, you are notified using Azure Monitor metrics.

Network Security Group (NSG)
NSGs operate at layers 3 & 4, and provide a list of allowed and denied communication to and from network interfaces and subnets. NSGs are fully customizable, and give you the ability to fully lock down network communication to and from your virtual machines. By using NSGs, you can isolate applications between environments, tiers, and services.

Authentication (Who are you?)
Authentication is the process of establishing the identity of a person or service looking to access a resource. It involves the act of challenging a party for legitimate credentials, and provides the basis for creating a security principal for identity and access control use. It establishes if they are who they say they are.

Authorization (What are you allowed to do?)
Authorization is the process of establishing what level of access an authenticated person or service has. It specifies what data they’re allowed to access and what they can do with it.

Azure Active Directory (Authentication, SSO, Application Management, B2B Identity Services, Device Management)
Azure AD is a cloud-based identity service. It has built in support for synchronizing with your existing on-premises Active Directory or can be used stand-alone. This means that all your applications, whether on-premises, in the cloud (including Office 365), or even mobile can share the same credentials. Administrators and developers can control access to internal and external data and applications using centralized rules and policies configured in Azure AD.
• Authentication
• Single Sign-On (SSO)

Azure ATP is capable of detecting known malicious attacks and techniques, security issues, and risks against your network.

Azure Policies
Azure Policy is a service you can use to create, assign, and manage policies. These policies apply and enforce rules that your resources need to follow. These policies can enforce these rules when resources are created, and can be evaluated against existing resources to give visibility into compliance.

Initiatives work alongside policies in Azure Policy. An initiative definition is a set or group of policy definitions to help track your compliance state for a larger goal.

Role-Based Access Control
RBAC provides fine-grained access management for Azure resources, enabling you to grant users the specific rights they need to perform their jobs. RBAC is considered a core service and is included with all subscription levels at no cost.

Resource Locks
Resource locks are a setting that can be applied to any resource to block modification or deletion. Resource locks can set to either Delete or Read-only. Delete will allow all operations against the resource but block the ability to delete it. Read-only will only allow read activities to be performed against it, blocking any modification or deletion of the resource. Resource locks can be applied to subscriptions, resource groups, and to individual resources, and are inherited when applied at higher levels.

4 Pricing and support

Azure Account
An Azure account is tied to a specific identity and holds information like: Name, email, and contact preferences; Billing information such as a credit card. An Azure account is what you use to sign in to the Azure website and administer or deploy services. Every Azure account is associated with one or more subscriptions.

Azure Free Account
• Subset of Azure services free for 12 months (750 VM hours, 5GB Storage, 250GB SQL DB, etc)
• $200 USD free credit (170 euro) to explore any Azure service for 30 days
• 25+ services always free

Azure Subscription
An Azure subscription is a logical container used to provision resources in Microsoft Azure. It holds the details of all your resources like virtual machines, databases, etc.

Azure Subscription – Use and Options
Azure offers free and paid subscription options to suit different needs and requirements. The most commonly used subscriptions are:
• Free: An Azure free subscription includes a $200 credit to spend on any service for the first 30 days, free access to the most popular Azure products for 12 months, and access to more than 25 products that are always free.
• Pay-As-You-Go: A Pay-As-You-Go (PAYG) subscription charges you monthly for the services you used in that billing period. This subscription type is appropriate for a wide range of users, from individuals to small businesses, and many large organizations as well.
• Enterprise Agreement: An Enterprise Agreement (EA) provides flexibility to buy cloud services and software licenses under one agreement, with discounts for new licenses and Software Assurance. It’s targeted at enterprise-scale organizations.
• Student: An Azure for Students subscription includes $100 in Azure credits to be used within the first 12 months plus select free services without requiring a credit card at sign-up. You must verify your student status through your organizational email address.
Every Azure Subscription Includes
• Free access to billing and subscription support
• Azure products and services documentation
• Online self-help documentation
• Community support forums
Purchasing Options for Azure Products and Services
• Enterprise: Enterprise customers sign an Enterprise Agreement (EA) with Azure that commits them to spend a negotiated amount on Azure services, which they typically pay annually. Enterprise customers also have access to customized Azure pricing.
• Web direct: Direct Web customers pay general public prices for Azure resources, and their monthly billing and payments occur through the Azure website.
• Cloud Solution Provider: Cloud Solution Provider (CSP) typically are Microsoft partner companies that a customer hires to build solutions on top of Azure. Payment and billing for Azure usage occur through the customer’s CSP.
Factors Affecting Costs
• Resource Type: Costs are resource-specific, so the usage that a meter tracks and the number of meters associated with a resource depend on the resource type.
• Service: Azure usage rates and billing periods can differ between Enterprise, Web Direct, and Cloud Solution Provider (CSP) customers. Some subscription types also include usage allowances, which affect costs.
• Location: Azure has datacenters all over the world. Usage costs vary between locations that offer particular Azure products, services, and resources based on popularity, demand, and local infrastructure costs.
A Zone is a geographical grouping of Azure Regions for billing purposes. The following zones exist and include the listed countries (regions) listed.
• Zone 1 (United States, Europe, Canada, UK, France)
• Zone 2 (Asia Pacific, Japan, Australia, India, Korea)
• Zone 3 (Brazil)
• DE Zone 1 (Germany)
Pricing Calculator
The Azure pricing calculator is a free web-based tool that allows you to input Azure services and modify properties and options of the services. It outputs the costs per service and total cost for the full estimate.

Total Cost of Ownership (TCO) Calculator
If you are starting to migrate to the cloud, a useful tool you can use to predict your cost savings is the Total Cost of Ownership (TCO) calculator. TCO helps you estimate cost savings realized by mirating to Azure.

Best Practices for Minimizing Azure Costs
• Spending Limits: Spending limit in Azure exists to prevent spending over your credit amount. All new customers who sign up for the trial or offers that includes credits over multiple months have the spending limit turned on by default. The spending limit is $0. It can’t be changed. The spending limit isn’t available for subscription types such as Pay-As-You-Go subscriptions and commitment plans.
• Quotas: Microsoft Azure Limits
• Tags: You can use tags to group your billing data. For example, if you’re running multiple VMs for different organizations, use the tags to group usage by cost center. You can also use tags to categorize costs by runtime environment, such as the billing usage for VMs running in the production environment. When exporting billing data or accessing it through billing APIs, tags are included in that data and can be used to further slice your data from a cost perspective.
• Reserved Instances
: Reserved instances are purchased in one-year or three-year terms, with payment required for the full term up front. After it’s purchased, Microsoft matches up the reservation to running instances and decrements the hours from your reservation. Reservations can be purchased through the Azure portal. And because reserved instances are a compute discount, they are available for both Windows and Linux VMs.
Azure Cost Management
Azure Cost Management is another free, built-in Azure tool that can be used to gain greater insights into where your cloud money is going. You can see historical breakdowns of what services you are spending your money on and how it is tracking against budgets that you have set. You can set budgets, schedule reports, and analyze your cost areas.
