Design high availability application on azure

Designing a high availability application on Azure involves implementing multiple components and strategies to ensure minimal downtime and maximum uptime. Here's a

comprehensive approach:

1. Regional Redundancy:

- Deploy resources across multiple Azure regions (e.g., US East, US West, EU).

- Use Azure Traffic Manager for global load balancing and routing.

2. Availability Zones:

- Deploy resources across multiple Availability Zones (AZs) within a region.

- Use Azure Load Balancer for intra-region load balancing.

3. Virtual Machine (VM) Redundancy:

- Create multiple VMs for each role (e.g., web server, database).

- Use Azure Availability Sets for VM grouping and fault tolerance.

4. Storage Redundancy:

- Use Azure Storage with geo-redundancy (GRS) or read-access geo-redundant storage (RA-GRS).

- Store data in multiple locations for high availability.

5. Database Redundancy:

- Use Azure Database Services with built-in high availability features (e.g., SQL Database, Cosmos DB).

- Implement database replication and failover strategies.

6. Load Balancing and Autoscaling:

- Use Azure Load Balancer for traffic distribution and autoscaling.

- Configure autoscale rules based on performance metrics.

7. Monitoring and Alerting:

- Use Azure Monitor for performance monitoring and alerting.

- Set up alerts for critical issues and implement automated remediation.

8. Disaster Recovery:

- Implement a disaster recovery plan with regular backups and snapshots.

- Use Azure Site Recovery for automated failover and recovery.

9. Security and Networking:

- Implement Azure Security Center for threat protection and monitoring.

- Configure network security groups (NSGs) and access controls. 10. Continuous Deployment and Integration:

- Use Azure DevOps for continuous integration and deployment (CI/CD).

- Implement automated testing and validation.

By following these guidelines, you can design a highly available application on Azure that minimizes downtime and ensures maximum uptime for your users.

Azure architect types

Azure architects can be categorized into several types based on their focus, expertise, and responsibilities. Here are some common Azure architect types:

1. Cloud Architect: Responsible for designing and building cloud-based systems, applications, and infrastructure on Azure.

2. Solutions Architect: Focuses on designing and implementing specific solutions on Azure, such as data analytics, AI, or IoT.

3. Enterprise Architect: Oversees the overall Azure strategy, governance, and architecture for an organization.

4. Application Architect: Designs and builds applications on Azure, focusing on software architecture, scalability, and performance.

5. Infrastructure Architect: Responsible for designing and managing Azure infrastructure, including virtual machines, storage, and networking.

6. Data Architect: Focuses on designing and implementing data storage, processing, and analytics solutions on Azure.

7. Security Architect: Ensures the security and compliance of Azure solutions, including identity, access management, and threat protection.

8. DevOps Architect: Focuses on implementing DevOps practices and tools on Azure, such as continuous integration and delivery.

9. Hybrid Architect: Designs and implements hybrid cloud solutions, integrating Azure with on-premises infrastructure and applications.

10. Azure Specialist Architect: Has deep expertise in specific Azure services, such as Azure Functions, Azure Kubernetes Service (AKS), or Azure Cosmos DB. Note that these types are not mutually exclusive, and Azure architects often take on multiple roles and responsibilities.

Design model for identity access on azure

Here is a high-level design model for identity and access management on Azure:

1. Identity Store

- Azure Active Directory (AAD) as the central identity store

- Integrate with on-premises Active Directory (AD) using Azure AD Connect

2. Authentication

- Azure AD authentication for users and services

- Multi-factor authentication (MFA) enabled for added security

- Support for external identity providers (e.g., Google, Facebook)

3. Authorization

- Role-based access control (RBAC) for resource access management

- Azure AD groups for grouping users and assigning permissions

- Attribute-based access control (ABAC) for fine-grained access control

4. Access Management

- Azure AD Privileged Identity Management (PIM) for elevated access management

- Just-in-time (JIT) access for temporary access to resources

- Access reviews and certification for ongoing access validation

5. Identity Protection

- Azure AD Identity Protection for anomaly detection and risk assessment

- Conditional access policies for adaptive access control

- Identity theft and fraud detection

6. Monitoring and Reporting

- Azure AD reporting and analytics for identity and access insights

- Integration with Azure Monitor and Azure Log Analytics for security monitoring

7. Identity Governance

- Identity lifecycle management (creation, update, deletion)

- Identity reconciliation and synchronization

- Identity data management and quality

This design model provides a comprehensive framework for managing identity and access on Azure, ensuring secure and authorized access to resources while meeting compliance and regulatory requirements.

Design network architect on azure

Here is a high-level design for a network architect on Azure:

Hub and Spoke Network Architecture

- Hub:

- Azure Virtual Network (VNet) with a central hub VNet

- Azure Firewall or Network Virtual Appliance (NVA) for security

- Azure Route Server for route management

- Spokes:

- Multiple VNets for different workloads or regions

- Peered with the hub VNet for connectivity

- Optional: NVAs or firewalls for additional security

Network Security

- Network Security Groups (NSGs): used to filter inbound and outbound traffic

- Azure Firewall: used for advanced threat protection and filtering

- Network Virtual Appliances (NVAs): used for additional security features

Routing and Connectivity

- Azure Route Server: used for route management and propagation

- Border Gateway Protocol (BGP): used for dynamic routing

- ExpressRoute: used for dedicated, high-bandwidth connectivity

Monitoring and Management

- Azure Network Watcher: used for network monitoring and diagnostics

- Azure Monitor: used for performance and security monitoring

- Azure Resource Manager (ARM): used for infrastructure-as-code management

Additional Components

- Azure Load Balancer: used for load balancing and traffic distribution

- Azure Application Gateway: used for web application security and delivery

- Azure DNS: used for domain name resolution and management

This design provides a secure, scalable, and manageable network architecture on Azure, with a hub and spoke model for connectivity and security, and additional

components for monitoring, management, and application delivery.

Scaling by adding additional instances is often referred to as scaling out

By adding and removing role instances to your Windows Azure application while it is running, you can balance the performance of the application against its

running costs.

High Availability --zero downtime

application updates,hardwarefailures,config,os updates

Microsoft Azure applies various replication and redundancy strategies to

make azure hosted services and applications as fault tolerant.

Public Cloud -- All components of your application/ system are running

in Azure only.

Private Cloud -- You are running Azure services and features within

on-premises data center

Hybrid Cloud -- Combination of Public and Private.

The web application in cloud service is

termed as "Web Role"

whereas background processing applications are

termed as "Worker Role". When we deploy web/ worker roles in cloud service is becomes PaaS offering

when we create virtual machines (by using

management portal, PowerShell, CLI, Rest API or Azure SDK) under a cloud

service becomes IaaS offerings

**Fault domain** is a physical unit of failure. **Upgrade Domain -** at

any point of time during upgrade at least one instance is alive and

serving the users request hence you don't face the downtime of your

application.

upgrade of guest OS, host OS or

application update

PaaS means you focus only on Application and Data

IaaS means you get support only virtualization

For achieving high availability in case of Azure IaaS VMs --

Availability sets should be used along with at least 2 instances of VMs

and implement this redundancy at every web tier and DB tier.
