Latency is a term used to describe the time it takes for data to travel. Regional low-latency network is a fiber connection between data centers in the region. We must choose a region closest to our users to minimize latency. Paired regions are usually within the same geographic area except for Brazil south, outage failover means if the primary region has an outage you can failover to the secondary region. Each region has a minimum of 3 zones. You need virtual machines in at least two of the data centers. Again, a region is a set of datacenters deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
The Azure Resource Manager (ARM) manages the portal, azure CLI, powershell, rest API, client SDK by handling the request. Choose creating a virtual machine. A virtual machine doesn't have its own exclusive hardware. Pros: control, application, existing infrastructure. Scale sets are a group of identical, load balanced VMs. Multiple VMs: simple to manage multiple identical VMs using a load balancer. Scale sets are identical VMs, they can be activated or deactivated as needed. A baseline VM for the scale set ensures application stability. A baseline VM is what you copy to make up the scale set VMs. As resource usage increases, more VMs are activated to take the load. You only pay for the VM, storage and networking resources you use. Nothing additional for scale sets. A virtual network gateway is composed of two or more virtual machines.
Containers are useful. When you have containers, you can manage application dependencies, there will be less overhead, increased portability. K8s = kubernetes = is an open-source container orchestration system for automating application deployment, scaling, and management. Azure K8s service replicate container architecture - can reuse your container architecture by managing it in k8s. This makes your setup quicker and confidence in the system increase. Elastic provisioning is resource management. Azure container registry (ACR) keep track of current valid container images.
Load Balancer distributes new inbound flows that arrive on the Load Balancer's frontend to backend pool instances, according to rules and health probes. Inbound flows: traffic from the internet or local network. Frontend: the access point for the load balancer. Backend pool: the VM instances receiving traffic. Rules & health probes: check to ensure backend instance can receive the data.
A Vnet belongs to a single region, every resource on the Vnet must be in the same region too. Each Vnet belong to just one subscription, but a subscription can have multiple Vnets. High availability needs peering Vnets, using a load balancer, or using a VPN gateway all increase availability. Isolation - manage and organize resources with subnets and network security groups.
Geo-Zone-Redundant storage (GZRS) allows three copies in primary regional physical location (LRS), three copies in secondary (paired) region physical location. Different solution based on transfer frequency, data size, network bandwidth. Ship Data Box to/from Azure. To azure: data box data transferred to storage account. From azure: data box delivered to on-prem location for on-site transfer.
CosmosDB, PostgreSQL are common databases that help with latency, connectivity. Develops choose from various software development kits (SDK) and API (application programming interface). MongoDB and Cassandra are platforms. There are two products, Azure SQL database and Azure SQL managed instance. MySQL Features are open-sourced, mySQL is an open source project where any member of the community can contribute. Relational database - data in the database is connected through relations in the data itself. Platform as a Service, the service infrastructure is managed by MS. Choice of language are PHP and WordPress. PostgreSQL has extensions, it uses a large number of extensions, such as JSONB, geospatial functions, indexing, integration with tools and much more. Horizontal scaling, uses very high performant access to distributed data sets.
IoT is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. IoT Central - Azure Sphere. Data Lake Analytics has parallel processing when there are two or more processes or computers processing the same data at the same time. Data Lake Analytics includes parallel processing.
Limitations of Azure AD and Cloud Migrations - legacy applications are unable to use modern authentication protocols (OAuth 2.0). They require traditional active directory (AD DS) management/protocols. Group policy, LDAP, NTLM, Kerberos, etc.
Firewalls define rules for what kind of traffic can and cannot access the device or service behind it. Distributed Denial of Service (DDoS). Too many server requests, all coming to a single server. Network Security Group (NSG) are resource firewalls, personal resource firewalls that are attached to virtual networks, subnet, or network interface. Another tool is Sentinel. Sentinel is a security information and event management (SIEM) tool that collects data, aggregates and normalizes, analyzes and detects threats, and take action.
Role-based access control (RBAC) is used to define user access, minimum access, target specific use cases. In the case of Azure governance, Azure Monitor generates logs and telemetry data, analyzing the data to gain valuable insights. VM disk size, VPN connection logs, and long term analysis. To maintain servers in both Azure and an on-premises datacenter, you want to apply Azure management services (azure blueprints, azure policy)
