General questions

QuestionAnswer

Are there any cache controls?

Yes. Normal cache control directives such as TTL are honored. Cloud Wrapper-specific cache control isn't supported. This includes:

  • Pre-warming
  • Cache retention configuration
  • Permanent caching

Can I manage individual cache objects?

No. Managing individual objects isn't supported.

Can I see what's in the cache?

No. You can't see individual objects.

Is there an object count limit?

Yes. Cloud Wrapper has a default object count limit of 10,000 objects/GB. Talk to your account team about acquiring additional space, if necessary.

Does Cloud Wrapper support advanced metadata configurations?

Yes. You need to contact your account team for assistance.

Does Cloud Wrapper support Enhanced TLS?

No. Currently, only ​Akamai​'s Standard TLS network is supported.

How long does data live in cache?

This depends on the traffic preference set for your LOCATIONS in your configuration—prefer low latency versus prefer redundancy. See TTL and object evictions for complete details.

Can I use a third-party CDN with Cloud Wrapper?

Yes. Cloud Wrapper supports these CDN providers:

  • AT&T
  • CacheFly
  • CloudFront
  • Comcast
  • Edgeio
  • Google
  • Fastly
  • HighWinds
  • Jio
  • Level3 (Centurylink)
  • Limelight
  • Line CDN
  • PicoNETS
  • Qwilt
  • StackPath
  • Verizon (VDMS)

📘

Currently, multi-CDN support is only offered with ​Akamai​'s Adaptive Media Delivery, Download Delivery, and Object Delivery products.

Are there traffic limits with Cloud Wrapper?

Yes. This varies, based on the type of Cloud Wrapper configuration:

  • Standard Cloud Wrapper configurations. ​Akamai​ may throttle traffic if there's a risk of it negatively impacting other customers' ability to access their Cloud Wrapper cache. Reach out to your ​Akamai​ account team for more information.
  • MultiCDN Cloud Wrapper configurations. ​Akamai​ enforces a default limit of 20 Gbps across all third-party content delivery networks. If you need your MultiCDN limit increased, reach out to your ​Akamai​ account team.

Is there an Access Control List (ACL) available for Cloud Wrapper?

Yes. You can add the Origin IP Access Control List (ACL) behavior to your property to use its ACL with your Cloud Wrappercache. See the Origin IP ACL documentation for complete details.

🚧

Origin IP Access Control List is not a substitute for authentication. To further enhance your origin security, use them in combination with authentication methods such as authentication tokens.

Can I set alerts for Multi CDN auth errors?

Yes. Configure them in the Alerts application. Create alerts for Edge Errors -- Content Delivery (HTTP 4xx and 5xx errors) using your Multi CDN CP codes. To receive auth failures at the earliest indication, set the threshold to a very low value (0.01% - 0.1%).

Cloud Wrapper & failover

Failover with Cloud Wrapper requires the Cloud Wrapper Advanced behavior.

QuestionAnswer

Does Cloud Wrapper work with Failover?

Yes. Cloud Wrapper supports failover for MultiCDN properties by default.

Is there a performance impact?

Possibly, in a specific scenario. There may be a performance impact if the failover map forwards requests to ​Akamai​ edge servers that are geographically further than your origin server location.

📘

This failover method prevents hits to origin. If you prefer going to origin to maintain performance, contact your account team to disable the failover workflow.

What if the failover map forwards to a different geo?

Increased costs may occur when a failover map forwards requests out of an existing low-cost geo. Note: We support per-geo failover maps to reduce the chance of this happening. Discuss these options with your account team.

Cloud Wrapper & purging

QuestionAnswer

Can I purge content by URL?

Yes. Purge and invalidate content by URL is the recommended method of purge for complete content removal. Purge by URL will remove content completely from ​Akamai​ cache, including Cloud Wrapper.

📘

This will impact ​Akamai​ delivery along with third-party delivery if the same objects are served using both workflows.

Can I purge content by CP Codes?

Yes. To ensure complete content removal, you must purge or invalidate all CP codes that serve your content, including both ​Akamai​ and third-party CDN CP codes.

Can I purge by Cache-Tag?

Yes. If you've enabled cache tags in your delivery configuration, you can purge content, based on a specific cache tag you've set.

Cloud Wrapper & support with other products

QuestionAnswer

Is Cloud Wrapper's cache space available for use with Image and Video Manager (IVM)?

Yes. Through the Cache+ functionality that's been added to support images with IVM, you can enable Cloud Wrapper in its behavior in your Ion or Dynamic Site Accelerator (DSA) property:

  1. Work with your ​Akamai​ account team to determine your capacity requirements for your site's image files.
  2. Add a Cloud Wrapper configuration.
  3. Activate your configuration.
  4. Create (or edit) an Ion or Dynamic Site Accelerator property.
  5. Add an Image and Video Manager rule to your property.
  6. Add the Image and Video Manager (Images) behavior to the rule. Toggle Cloud Wrapper to On. Set all other options as necessary.

📘

  • In this scenario, you don't need to add the Cloud Wrapper behavior to your Ion/DSA property.
  • Cloud Wrapper's caching space is currently only available for use with image files in IVM.

Cloud Wrapper status

Your configuration status follows this table of definitions:

ActionStatusDescription
SaveSavedThis is the initial state when your configuration version is saved.
ActivateActivation In ProgressYour activation request is being processed. Propagation time is approximately 3-4 hours.
ActivateActivation Failed 1 2Your activation request has failed. Create a new configuration version and try again.
ActivateActivation Aborted 2Your activation request has been aborted.
ActivateActive 2This configuration is now active. Note: Use Property Manager to apply this configuration to a behavior .
DeleteDelete In ProgressYour request to delete this configuration is being processed.
DeleteDelete Failed 1 2Your request to delete this configuration has failed.
DeleteDelete Aborted 2Your request to delete this configuration has been aborted.
N/AInactivePreviously Active versions are displayed as Inactive when the latest version becomes active.

1 The system automatically removes this configuration version.
2 The system sends a notification to the email associated with your ​Akamai Control Center​ login.

TTL and object evictions

Cloud Wrapper uses two methods to determine eviction:

  • Cloud Wrapper cache space is full. Cloud Wrapper uses the LRU (“least recently used”) algorithm for evicting content once space is full. The eviction is based on the last time an object was accessed, with the oldest-accessed time getting evicted first.

  • Idle objects. Cloud Wrapper applies a platform-level eviction after an asset is not accessed in your cache for a certain amount of time. We call this its idle time to live (TTL). This time varies based on the Traffic Preference you've set for the Location in your configuration:

    • Prefer Low Latency. This applies to live streaming media assets delivered through ​Akamai​'s Adaptive Media Delivery (AMD) product. Low latency content that isn't accessed for three days is considered idle.

    • Prefer Redundancy. This applies to static assets like on-demand video via AMD, downloadable assets via Download Delivery or Object Delivery, or website content via Ion or Dynamic Site Accelerator. Redundant content that isn't accessed for 30 days is considered idle. This can be overridden with the Retain Idle Objects option.

📘

Low idle TTL doesn't automatically result in an object eviction

If an object's idle TTL is low, Cloud Wrapper flags it, but doesn't evict it. It's only evicted if your cache space is close to full, or if it's reached its full idle TTL.

Cloud Wrapper locations

Your initial location and size mapping is done by your account team. Work with them to determine which Cloud Wrapper location is best for you.

  • Brazil
  • Europe
  • Hong Kong
  • India
  • Japan
  • Japan + Singapore (Dualmap)
