This approach allows for the replication of resources 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. Composite SLA ✔✔When combining SLAs across different service offerings, the resulting SLA can provide higher or lower up time values, depending on your application architecture. Resiliency ✔✔The ability of a system to recover from failures and continue to function. It's not about avoiding failures, but responding to failures in a way that avoids downtime or data loss. Availability ✔✔Refers to the time that a system is functional and working. Maximizing availability requires implementing measures to prevent possible service failures.
Azure Account ✔✔An identity in either Azure AD, or a directory that is trusted by Azure AD, such as a work or school organization. It holds information such as: Name, email, contact preferences, and billing information such as a credit card. It will always be associated with one or more subscriptions within Microsoft Azure. Azure Subscription ✔✔a logical container used to provision resources in Microsoft Azure. It holds the details of all your resources like virtual machines, databases, and so on. Every Azure subscription is associated with Azure AD. Users and services that access those resources first need to authenticate with Azure AD. Tenant ✔✔A dedicated, isolated instance of the Azure Active Directory service, owned and managed by an organization. Defense in Depth ✔✔A strategy that employs a series of mechanisms to slow the advance of an attack aimed at acquiring unauthorized access to information. Each layer provides protection so that if one layer is breached, a subsequent layer is already in place to prevent further exposure. Azure Security Center ✔✔A monitoring service that provides threat protection across all of your services both in Azure, and on-premises. Authentication ✔✔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 ✔✔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 ✔✔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. Multi-factor Authentication ✔✔Multi-factor authentication (MFA) provides additional security for your identities by requiring two or more elements for full authentication. These elements fall usually into three categories: Something you know. Something you possess. Something you are. Role-Based Access Control ✔✔Ensures that the user gains access only to the resources that the user should be able to access
Azure Logic Applications ✔✔Very similar to Azure Functions - both enable you to trigger logic based on an event. While Azure Functions execute code, this lets you execute work flows designed to automate business scenarios and built from predefined logic blocks. The work flow starts with a trigger, which fires when a specific event happens or when newly available data meets specific criteria. Many triggers include basic scheduling capabilities, so developers can specify how regularly their workloads will run. Azure Blob Storage ✔✔Microsoft's object storage solution for the cloud. It's optimized for storing massive amounts of unstructured data. Route Table ✔✔Azure automatically routes traffic between Azure subnets, virtual networks, and on-premises networks. If you want to change any of Azure's default routing, you do so by adding this tool to your Azure Networking infrastructure. Network Security Group ✔✔Contains security rules that allows you to filter network traffic, approve or deny inbound/outbound network traffic to and from an Azure resources inside of an Azure virtual network. Azure Activity Log ✔✔Provides insight into subscription-level events that have occurred in Azure. This includes a range of data, from Azure Resource Manager operational data to updates on Service Health events. Azure Active Directory ✔✔Microsoft's cloud-based identity and access management service, which helps your employees sign in and access resources. Both Basic and Premium come with a 99.9% Uptime Guarantee SLA. Azure Support ✔✔All Service Plans outside of the basic service plan are available for Microsoft Azure support. This will give you access to receive support from Microsoft Azure experts when you require it. Structured Data ✔✔Data that adheres to a schema, so all of the data has the same fields or properties. It can be easily stored in a database table with rows and columns. May also be referred to as relational data, as the data's schema defines the table of data, the fields in the table, and the clear relationship between the two. Semi-Structured Data ✔✔Data that doesn't fit neatly into tables, rows, and columns. Instead, it uses tags or keys that organize and provide a hierarchy for the data. Also could be referred to as non-relational or NoSQL data. Un-structured data ✔✔Encompasses data that has no designated structure to it. This lack of structure also means that there are no restrictions on the kinds of data it can hold. For example, it can hold a PDF document, a JPG image, a JSON file, and video content, etc. As such, it's becoming more prominent as businesses try to tap into new data sources.
Azure SQL Database ✔✔A relational database as a service (DaaS) based on the latest stable version of the Microsoft SQL Server database engine. It's a high-performance, reliable, fully managed and secure database. You can use it to build data-driven applications and websites in the programming language of your choice without needing to manage infrastructure. Microsoft Data Migration Assistant ✔✔A service to generate assessment reports that provide recommendations to help guide you through required changes prior to performing a migration. Once you assess and perform any re-mediation required, you're ready to begin the migration process. The service will perform all of the required steps. Leaving the only thing for you to do is update the connection strings in your applications. Azure Data Lake Storage ✔✔Combines the scalability and cost benefits of object storage with the reliability and performance of the big data file system capabilities.
