If you choose to upload certificate, upload the PEM certificate file that is to be used to connect to the on-premises system.





* You can verify your certificate file using following command:

openssl s_client -CAfile <CA> -connect <target_host>:<target_port>

Where: CA is the certificate file you uploaded, target is the on-premise endpoint.









 How can I interactively load an ACL file in the Docker client? 



 What is happening 

Since Docker is a container or virtualized environment, it does not have direct access to your filesystem until the container is actually launched. This prevents it from reading your host machines filesystem until it is actually launched and running.





 How to fix it 

This is what you can do:



* Create a Dockerfile to include the aclfile.txt



FROM ibmcom/secure-gateway-client
ADD aclfile.txt /tmp/aclfile.txt



* Build a new docker image



docker build -t ads-secure-gateway-client .



* Run new docker image (need to specify -t and -i options, otherwise you will get error, file not found or ENOENT):



docker run -t -i ads-secure-gateway-client1 --F /tmp/aclfile.txt



* You should get the following output:



[2015-09-30 16:50:32.084] [INFO] The current access control list is being reset and replaced by the user provided file: /tmp/aclfile.txt
[2015-09-30 16:50:32.086] [INFO] The ACL file process accepts acl allow :8000
[2015-09-30 16:50:32.087] [INFO] The ACL file process accepts acl deny local







 Why do I get 401 Unauthorized when accessing Secure Gateway gateway panel? 



 What is happening 

When you access the Secure Gateway instance via the url https://cloud.ibm.com/services/securegateway/<sg_instance_id>?env_id=<region>, and you receive the error message 401 Unauthorized.
Private load balancer names can be resolved publicly, but the addresses they resolve to are not routable from the internet, and can only be reached from inside your own private network environment.
* Does the NLB support layer 7 switching?

No. The network load balancer does not support layer 7 switching.
* What's the maximum number of front-end listeners I can define with my load balancer?

You can define a maximum of ten front-end listeners for an NLB.
* What's the maximum number of virtual server instances I can attach to my back-end pool?

You can attach a maximum of 50 virtual server instances to your back-end pool for a network load balancer.
* Is an NLB horizontally scalable?

No. A network load balancer is not horizontally scalable.
* What are the default settings and allowed values for health check parameters?

The following default settings apply to network load balancer health check parameters:



* Health check interval: Five seconds, and the range is 2 - 60 seconds.
* Health check response timeout: Two seconds, and the range is 1 - 59 seconds.
* Maximum retry attempts: Two retry attempts, and the range is 1-10 retries.



The health check response timeout value must be less than the health check interval value.
* Is the network load balancer IP address fixed?

The IP address is fixed for both public and private network load balancers. However, route mode NLBs toggle between primary and standby appliance IPs throughput their lifetime.
* Does IBM complete quarterly ASV scans of data-plane LBaaS appliances?

Approved Scanning Vendor (ASV) quarterly scanning is a requirement of the Payment Card Industry (PCI) Security Standards Council. ASV scanning of LBaaS data-plane appliances is solely a customer responsibility. IBM does not use ASVs to scan data-plane appliances because these scans can negatively impact customer workload functions and performance.
* What is a snapshot?

Snapshots are a point-in-time copy of your Block Storage for VPC boot or data volume that you manually create. To create a snapshot, the original volume must be attached to a running virtual server instance.
* Is there any additional cost associated with using a DV SAN certificate for my CDN?

No. DV SAN certificate configurations are provided to you at no additional charge that is compared with HTTP or HTTPS with a Wildcard certificate.
* Can my CDN created using HTTPS with Wildcard be updated to use a DV SAN certificate?

No, a wildcard mapping cannot be changed to SAN certificate.
* What is a certificate authority?

A certificate authority (CA) is an entity that issues digital certificates.
* Which CA does IBM Cloud® CDN service use for issuing a DV SAN certificate?

IBM Cloud CDN service uses LetsEncrypt certificate authority.
* What SSL certificates are supported for IBM Cloud CDN?

The SSL certificates that are supported are Wildcard certificate and Domain Validation (DV) Subject Alternate Name (SAN) certificate. The SAN certificate is shared across multiple customers. IBM Cloud CDN does not support uploading custom certificates.
* I received an email asking me to address a Domain Validation challenge that is related to my CDN. What do I do now?

Domain Validation can be addressed in one of three ways: CNAME, Standard, or Direct.

For details on how to address any of these, refer to the [Completing Domain Control Validation for HTTPS](https://cloud.ibm.com/docs/CDN?topic=CDN-completing-domain-control-validation-for-https-with-dv-saninitial-steps-to-domain-control-validation) document.
* What will happen if I don't address the challenge for domain validation of my CDN?

If the mapping's state is in DOMAIN_VALIDATION_PENDING state for more than 48 hours, the mapping creation is cancelled, and the mapping's state will be CREATE_ERROR. And in this state, you can choose to Retry creation or delete the mapping.
* Does a Wildcard certificate need to validate a domain for my CDN?

No, but you can only use the CNAME to retrieve content from your origin. For example, https://www.example-cname.cdn.appdomain.cloud.
For more information, see [Tags for Block Storage for VPC volumes](https://cloud.ibm.com/docs/vpc?topic=vpc-block-storage-about&interface=uistorage-about-tags).
* What is IOPS and how do it relate to my Block Storage for VPC volume performance?

 What is IOPS and how do it relate to my Block Storage for VPC volume performance? 

Input/output operations per second (IOPS) is used to measure the performance of your Block Storage for VPC volumes. A number of variables impact IOPS values, such as the balance of read/write operations, queue depth, and data block sizes. In general, the higher the IOPS of your Block Storage for VPC volumes, the better the performance. For more information about expected IOPS for Block Storage for VPC profiles, see [Profiles](https://cloud.ibm.com/docs/vpc?topic=vpc-block-storage-profiles). For more information about how block size affects performance, see [Block storage capacity and performance](https://cloud.ibm.com/docs/vpc?topic=vpc-capacity-performancehow-block-size-affects-performance).
* Is the allocated IOPS enforced by instance or by volume?

 Is the allocated IOPS enforced by instance or by volume? 

IOPS is enforced at the volume level.
* What are IOPS profiles and how do they affect volume performance?

 What are IOPS profiles and how do they affect volume performance? 

IOPS profiles define IOPS/GB performance for volumes of various capacities. You can select from three predefined [IOPS tiers](https://cloud.ibm.com/docs/vpc?topic=vpc-block-storage-profilestiers) that offer reliable IOPS performance for your workload requirements. You can also define [custom IOPS](https://cloud.ibm.com/docs/vpc?topic=vpc-block-storage-profilescustom) and specify a range of IOPS for a volume size that you choose.
* vCenter Server - Use the VMware Solutions console to provision an IBM-hosted private cloud based on vSphere, NSX, and optionally vSAN. For more information, see [vCenter Server overview](https://cloud.ibm.com/docs/vmwaresolutions?topic=vmwaresolutions-vc_vcenterserveroverview).



Upgrade and migration processes vary depending on the consumption model.





 What is the impact if I don't upgrade vSphere 6.x on my IBM Cloud bare metal hosts? 

Upgrading your vSphere software is a customer responsibility and the decision to upgrade to a supported version is yours. However, your business might be at risk because VMware is under no obligation to provide product patches and updates, such as security updates and bug fixes. If IBM Cloud provides your vSphere licenses, then IBM Support cannot assist you with vSphere issues until you upgrade.

FAQs for application load balancers 

The following sections contain answers to some frequently asked questions about the IBM Cloud® Application Load Balancer for VPC (ALB).



 Can I use a different DNS name for my ALB? 

The auto-assigned DNS name for the application load balancer is not customizable. However, you can add a CNAME (Canonical Name) record that points your preferred DNS name to the auto-assigned load balancer DNS name. For example, your load balancer in us-south has ID dd754295-e9e0-4c9d-bf6c-58fbc59e5727, and the auto-assigned load balancer DNS name is dd754295-us-south.lb.appdomain.cloud. Your preferred DNS name is www.myapp.com. You can add a CNAME record (through the DNS provider that you use to manage myapp.com) pointing www.myapp.com to the load balancer DNS name dd754295-us-south.lb.appdomain.cloud.





 What's the maximum number of front-end listeners I can define with my application load balancer? 

10 is the maximum number of front-end listeners that you can define with your ALB.





 What's the maximum number of virtual server instances I can attach to my back-end pool? 

50 is the maximum number of virtual server instances that you can attach to a back-end pool.





 What's the maximum number of subnets I can attach to my application load balancer? 

15 is the maximum number of subnets that you can define with your ALB.





 Is the load balancer horizontally scalable? 

Yes. The Application Load Balancer for VPC automatically adjusts its capacity based on the load. When horizontal scaling takes place, the number of IP addresses associated with the application load balancer's DNS changes.





 What do I do if I use ACLs on the subnets that are used to deploy the application load balancer? 

Make sure that the proper ACL rules are in place to allow incoming traffic for configured listener ports. Traffic between the application load balancer and back-end instances need also be allowed.
