Answer 3

Azure API Management integrates with Application Insights to provide real-time monitoring of API calls. By enabling the integration, you can track performance metrics, request and response data, dependencies, and exceptions. This helps in diagnosing issues, understanding usage patterns, and improving API reliability.

Question 4

For Azure API Management, how dose it integrate with Defender for APIs in Microsoft Defender for Cloud (Boost your API security)?

Answer 4

Azure API Management integrates with Defender for APIs in Microsoft Defender for Cloud by automatically identifying APIs managed by API Management and monitoring them for potential security threats. Defender for APIs enhances security by detecting anomalies, protecting against malicious activities, and offering insights to improve API configurations. This integration helps enforce security policies, ensuring better protection across Azure environments.

Question 6

What is the purpose of API gateway?

Answer 6

API Gateway component of Azure API management is responsible for handling incoming requests and routing them to the backend. Applying rate limiting, auth and authorization an,, transformations, load balancing, caching,.

Question 7

Can you have multiple gateways in the Azure APIU Services?

Answer 7

Isolating: environment for separate testing, deployments, etc.
Scalability: The ability to separate to handle load
Custom configurations
Compliance requirements

Question 8

Answer 9

Azure API Management, the API gateway is deployed across zones in a single region.

Question 10

What is a Azure API Management service unit?

Answer 10

Azure API Management service unit is a unit of scale for Azure API Management, it defines how much capacity your Azure API Management has to service requests.

Basic Tier:
Estimated Throughput: Approximately 1,000 requests per second per unit.
Features: Suitable for entry-level production use cases.

Standard Tier:
Estimated Throughput: Approximately 2,500 requests per second per unit.
Features: Designed for medium-volume production use cases.

Premium Tier:
Estimated Throughput: Approximately 4,000 requests per second per unit.
Features: Supports high-volume or enterprise production use cases, including multi-region deployments and virtual network integration.

Question 11

What are the tiers for Azure API Management?

Answer 11

Consumption (pay-as-you-go)
Basic Tier
Standard Tier
Premium Tier
Isolated Tier (preview)

Question 12

What is an Azure API Management policy?

Answer 12

An Azure API Management (APIM) gateway policy is a set of rules that modify the behavior of APIs at runtime. Policies allow administrators to control aspects such as request/response format, security, and performance.

Access Control: Restrict access based on IP, authentication, or API keys.

Rate Limiting: Limit API call frequency to manage traffic and prevent abuse.

Caching: Cache responses to reduce load on backend services.

Transformation: Modify requests and responses (e.g., changing formats).

Logging and Monitoring: Track requests and responses for analysis.

Error Handling: Customize error responses for client-friendly communication.

Security: Add security layers like token validation and IP filtering.

Question 13

What would i use to restrict access when using Azure API Management?

Answer 13

The Azure API Management Gateway policy

Question 14

What would i use to rate limit when using Azure API Management?

Answer 14

The Azure API Management Gateway policy

Question 15

What would i use to set up caching when using Azure API Management?

Answer 15

The Azure API Management Gateway policy

Question 16

When using Azure API Management can i configure and use caching?

Answer 16

Yes, caching is supported and can be configured using policies

Question 17

When using Azure API Management can i configure and use rate limiting?

Answer 17

Yes, rate limiting is supported and can be configured using policies

Question 18

When using Azure API Management can i configure and use transformation of the incoming request?

Answer 18

Question 19

Are both External and Internal VNet integration modes supported for the developer tier?

Answer 19

Yes

Question 20

Are both External and Internal VNet integration modes supported for the premium tier?

Answer 20

Yes

Question 21

Are both External and Internal VNet integration modes supported for the standard tier?

Answer 21

Standard v2 Tier: This tier supports VNet Integration, which allows APIM to access resources within a VNet. However, the APIM endpoints remain publicly accessible; fully private deployments (Internal mode) are not supported in this tier

Question 22

Are External and Internal VNet integration modes supported for the primary and standard tiers?

Answer 22

No

Question 23

I have a VM scale set deployed in a vNET, and I want to have API Manager access through the internal application gateway already deployed and working with the VM muscle set. I only wnat internal developers access to the portal using the internal network. How can I do this?

Answer 23

Internal VNet Mode: Here, APIM is deployed within a VNet, and its endpoints are accessible only from within the VNet or through connected networks like on-premises systems via VPN or ExpressRoute. This mode is ideal for scenarios requiring heightened security, where APIs should not be exposed to the public internet.

Question 24

I have a VM scale set deployed in a vNET, and I want to have API Manager access through the internal application gateway already deployed and working with the VM muscle set. I only wnat internal developers access to the portal using the internal network. How can I do this?

Answer 24

External VNet Mode: In this configuration, APIM is deployed within a VNet, allowing it to access resources inside the network. However, its endpoints—such as the API gateway and developer portal—remain accessible from the public internet. This setup is beneficial when you want to expose your APIs publicly while still accessing internal resources securely.
