Note

For additional information about Acquia Cloud Platform, see its product documentation.

Last updated: November 23, 2020

Acquia will provide the PaaS services described below only if purchased by Customer, as indicated in the Order.

Acquia Cloud Platform Enterprise is a managed Platform as a Service for Customer’s Drupal website(s). Acquia Cloud Platform Enterprise includes all the features of Acquia Cloud Platform, is subject to the Service Level Policy, and includes the additional features set forth below.

1. Platform Services

1.1. Drupal Services

Acquia will maintain Customer’s Drupal applications on the Platform during the Subscription Term in the Region as indicated in the Order. Customer may submit an unlimited number of support requests related to the Platform. Such tickets will not be counted towards the Support Services ticket allotment (if applicable) unless such issue was caused by an error in Customer’s website(s). Acquia will conduct daily backups of the Drupal application and related databases for disaster recovery purposes. Customer may also perform on-demand backups and restores.

1.1.1. Drupal Migration Services

Acquia will work with the Customer to migrate the website(s) onto the Platform. Once migrated, Acquia will conduct a light infrastructure audit of the website to determine whether any issues with the website may cause the launch to be unsuccessful. Following such audit, Acquia will disclose any launch blockers to Customer. Customer may elect to fix the launch blockers or engage Acquia at its standard consulting services rates to fix the blockers. If Customer elects not to correct the launch blockers identified by Acquia, any unavailability due to such launch blockers will not be counted when determining unavailability of the website pursuant to the Service Level Policy. Customer may purchase a full infrastructure site audit for an additional fee and subject to a separate Order.

1.2. Node.js Services

Acquia Cloud Platform provides application platform services for Node.js applications. Deploying Node.js applications on Acquia Cloud Platform requires that the Customer purchase a Node.js platform package along with their Acquia Cloud Platform Enterprise subscription.

The Node.js Service has four main components:

  • Source code repository service: Enables developers to track and manage multiple versions of the application
  • Automated build and deployment service: Deploys build artifacts to the development and production environments
  • Node.js development environment: For development activities by Customer’s Acquia Cloud Platform users
  • Node.js production environment: For production deployment

The Node.js Service includes support for the services listed above and the underlying platform infrastructure. Support for Customer’s Node.js application code and any third-party dependencies deployed by the Customer isn’t included.

1.3. Platform CDN Service

Acquia provides an integrated content delivery network (CDN) that customers may use to accelerate the delivery of web assets. The Platform CDN leverages global points of presence (POPs) to help customers deliver faster experiences, no matter where their users are located. Use of the Platform CDN requires customers to make authoritative DNS configuration changes to direct visitor requests to the customer domain through the CDN. The CDN is managed by Acquia and does not support any custom configuration. Customers may control the caching behavior of the Platform CDN through HTTP Cache-Control headers and Drupal tag-based invalidation, and full purge of the CDN cache. The Platform CDN does not support the customer’s custom VCL configurations at the CDN or the Acquia Cloud Platform Varnish tiers, or “stacked” CDN implementations where a reverse proxy-based CDN or WAF service is configured in front of or behind the Platform CDN.

For all Acquia Cloud customers who have elected to utilize the Platform CDN, the following Fair Use policy will apply:

  • Bandwidth: Monthly bandwidth usage on Platform CDN is limited to 200 GB. If a customer exceeds this limit for two or more consecutive months, then that customer must engage with an Acquia Account Manager to explore Acquia Edge CDN as an alternative solution to Platform CDN. Should Acquia Edge CDN fail to meet the needs of the customer, additional bandwidth may need to be purchased.
  • Domains: Customers may configure up to ten (10) domains for the Platform CDN per subscription. If a customer exceeds this limit for two or more consecutive months, then that customer must engage with an Acquia Account Manager to explore Acquia Edge CDN as an alternative solution to Platform CDN. Should Acquia Edge CDN fail to meet the needs of the customer, additional domains may need to be purchased.
  • SSL certificates: Customers may install up to ten (10) SSL certificates for the Platform CDN per subscription. If a customer exceeds this limit for two or more consecutive months, then that customer must engage with an Acquia Account Manager to explore Acquia Edge CDN as an alternative solution to Platform CDN. Should Acquia Edge CDN fail to meet the needs of the customer, additional certificates may need to be purchased.
  • No usage: If a customer enables the Platform CDN but does not make the DNS configuration changes required to direct visitor traffic through the CDN resulting in the customer domain receiving no Platform CDN traffic for two or more consecutive months, Acquia will remove the customer domain receiving no traffic from Platform CDN.
Item Limit Implications
Bandwidth 200 GB/month Acquia Account Manager will engage with the customer to explore upgrade to Acquia Edge CDN
Domain 10 Acquia Account Manager will engage with the customer to explore upgrade to Acquia Edge CDN
SSL certificate 10 Acquia Account Manager will engage with the customer to explore upgrade to Acquia Edge CDN
Cache file size 20 MB Exceeding this limit when trying to cache a file results in a 503 Response object too large error
Vary objects count 200 soft, 400 hard Exceeding the soft limit results in no error. Newer variants displace the oldest. Active fetches from backend are limited to 400 variants. Exceeding this hard limit results in a Too many variants response. Once the fetches complete, objects will be removed until the soft limit is reached.
URL size 8 KB Exceeding the limit results in a Too long request string error
Cookie size 32 KB Exceeding the limit results in Platform CDN stripping the cookie and setting req.http.Fastly-Cookie-Overflow = 1
Request header size 69 KB Depending on the circumstances, exceeding the limit can result in Platform CDN closing the client connection abruptly, or it can result in the client either receiving a 502 Gateway Error response with an I/O error in the body, or receiving a 503 Service Unavailable response with a Header overflow error in the body.
Response header size 69 KB Exceeding the limit results in a 503 backend read error. See Common 503 errors for more info.
Request header count 96 Exceeding the limit results in a Header overflow error. A small portion of this limit is reserved for internal Platform CDN use, making the practical limit closer to 85.
Response header count 96 Exceeding the limit results in a Header overflow error. A small portion of this limit is reserved for internal Platform CDN use, making the practical limit closer to 85.
req.body size 8 KB Exceeding the limit results in the req.body variable being blank. Request body payload is available in req.body only for payloads smaller than 8 KB. req.postbody is an alias for req.body.
Surrogate key size 1 KB Exceeding the limit results in purging API failures stating “Surrogate key too long, must be less than 1024 bytes.” Any keys that exceed the limit will be dropped instead of truncated.
Surrogate key header size 16 KB Exceeding the limit results in no error and any keys past the one that exceeds the limit will be dropped.

2. Drupal Web Server Administration Tasks

Acquia Cloud Platform Enterprise includes the following web server administration tasks:

  • Review system logs to diagnosis issues or upon request
  • Adjustments to Apache, MySQL, and PHP configuration including:
    • Changes for service diagnostics, deployment of new websites/Code Bases
    • apache.conf changes (such as modify conf change Code Base locations and add new sites)
    • php.ini changes (such as adjust memory limit or enable error logging)
    • my.cnf changes (such as enable slow query logs or modify slow query time)
    • Updates or upgrades to Apache, PHP, databases, or the operating system
  • LAMP stack changes pertaining to performance tuning
  • Installing or upgrading server applications

3. Backup and Disaster Recovery for Acquia Cloud Platform Enterprise

3.1. Data Centers

The Acquia Cloud Platform Enterprise Platform is physically remote from Acquia’s office facilities. A disaster affecting one or more of Acquia’s offices would not impact the availability of Customer website(s) or Customer Data. The Acquia Cloud Platform Enterprise environment consists of major Regions and Availability Zones. Availability Zones are separate yet interconnected data centers within major Regions in Acquia’s global infrastructure. Acquia Cloud Platform Enterprise utilizes a highly available redundant architecture that distributes replicated redundant server types (load balancing, caching, web and database servers) across multiple Availability Zones within the same Region. Acquia will use commercially reasonable efforts to restore the services in an alternate Availability Zone within the same Region (or alternate Region if Multi-Region Failover service has been purchased) in the event service in Customer’s assigned Availability Zone (or Region) is severely impacted.

3.2. Backups

Acquia will maintain a comprehensive backup solution which includes website code, static assets/files, and databases. Acquia will export MYSQL database one time per day and retain these backups for three days. Customer may also make on-demand backups of any database at any time on the workflow tab of the Acquia Cloud Platform user interface, or using SSH/SCP. During the Subscription Term, Acquia will retain these on-demand backups for Customer until Customer chooses to delete them. Backups will count against the storage space purchased in Customer’s Order. Customer may download these database backups and restore a previous backup on the backups tab of the Acquia Cloud Platform user interface. At the Drupal code layer, Customer-developed code may be managed and deployed by Customer using Acquia’s Git code repository service. This service allows Customer to roll-back and re-deploy the Drupal code, effectively backing up the Drupal layer so that the website code may be re-deployed to a new web server instance as needed. In addition, Acquia conducts daily backups of each website’s files and maintains a complete and current copy of each website, which will be used in the event Acquia must restore the website due to a failure of the Service. Backups are performed daily over the previous week, weekly over the previous month, and monthly thereafter.

3.3. Disaster Recovery

The Acquia Cloud Platform Enterprise Platform will make hourly internal disaster recovery snapshots of Customer Data. Acquia will retain these snapshots on a diminishing schedule for three months. These backups will be used to restore Customer website(s) at another location within the same Region in the event of a total data center loss or a loss of multiple disk systems. Acquia will not provide Customer access to these snapshots and will not use these snapshots to restore websites due to data-loss or deletion by Customer.


4. Server Capacity

4.1. Emergency Capacity

In the event Acquia becomes aware that Customer’s instances become, or may become overloaded due to greater than normal usage, Acquia will notify Customer and will take reasonable actions to increase the server capacity in an effort to maintain website performance. Customer agrees that Acquia, in its reasonable discretion, can unilaterally add capacity up to three-times the procured capacity, at Acquia’s then current daily rates. Such additional capacity will remain provisioned for a minimum of five calendar days. In the event Acquia determines that such additional capacity is necessary to maintain website performance for the remainder of the Term, Acquia will contact Customer to obtain approval to increase their server capacity. If, despite reasonable notification from Acquia that failure to upgrade the server is adversely impacting availability and Customer fails to upgrade, Acquia may downsize the server capacity to the original contracted amount. Acquia reserves the right to not provision additional server capacity if Customer has any outstanding amounts due or if it determines that additional capacity is unlikely to significantly improve performance, including, without limitation, when the overload is caused by an error in Customer’s software (for example, PHP code), Customer Drupal Instance or during a denial-of-service attack. Acquia reserves the right to bill Customer for traffic associated with a denial-of-service attack.

4.2. Emergency Storage Capacity Increase

In the event Acquia becomes aware that Customer’s instances have reached, or may reach, their allocated storage capacity, Acquia will notify Customer and will take reasonable actions to increase the storage capacity in an effort to maintain website availability. Customer agrees that Acquia, in its reasonable discretion, can unilaterally increase storage to the next standard storage size available at Acquia’s then current daily rates. Such additional storage capacity will remain provisioned for the remainder of the Term. Customer agrees to pay for such additional storage capacity for the remainder of the Term. Acquia reserves the right to not provision additional storage capacity if Customer has any outstanding amounts due. Acquia reserves the right to remove Customer from monitoring in the event that a recommended or completed storage capacity increase is refused or otherwise disputed by Customer. Downtime incurred while Customer instances are out of monitoring will be excluded from service level policy calculations.

4.3. Additional Capacity

Customer may request Acquia to increase their server capacity upon prior written request. Acquia will also make reasonable efforts to contact Customer when it is determined a server upgrade is needed. Any additional servers provisioned will be billed at the then current daily rates for a minimum of five calendar days. If Customer requests additional capacity to the Platform for two (2) consecutive months, such capacity will remain at such level for the remainder of the Subscription Term.

4.4. Shared Environments

If Customer is on shared development or staging environments, Customer acknowledges that such environments are only for low impact testing and development activities. Should Customer’s use of the shared development or staging environment adversely impact server performance, Customer will be required to move to a dedicated environment and will need to pay the associated server fees. Furthermore, Customer will not perform any load tests or vulnerability tests on live website(s) unless it has purchased dedicated servers and will provide Acquia at least five (5) business days advance notice of any such testing.

4.5. Server Capacity

If Customer regularly consumes (for example, more than two times in any week) more than 20% of the shared server capacity (CPU, memory, disk, PHP processes) assigned to Customer based on the information provided to Acquia on the Platform Questionnaire, Customer understands that Acquia may provision additional capacity for Customer and/or move Customer to a dedicated server instance at Customer’s expense. Acquia reserves the right to change the underlying infrastructure at any time as long as benchmark performance isn’t degraded​.​

4.6. Acquia Cloud Platform CD environments

Acquia Cloud Platform CD environments (CDEs) are on-demand development environments available as part of Acquia Cloud Platform CD subscriptions and can be added to Acquia Cloud Platform Enterprise subscriptions. CDEs enable a Customer to dynamically create new environments and deploy code, data and files to those environments in a self-service model. A Customer will be provided the ability to create CDEs up to the number specified within the Customer’s Order. Acquia Cloud Platform CD has two components:

  • CD environments (CDEs): For rapid creation of development environments
  • CD pipelines: For continuous delivery activities

Note

CD environments in Acquia Cloud are not meant to be used with production data or to store production data, especially if your application must adhere to compliance standards such as PCI, HIPAA, or FedRAMP.


5. Capacity Management

5.1. Traffic Capacity

Each Acquia Cloud Platform subscription includes a traffic capacity entitlement to support traffic up to the number of monthly views and unique visits (each as defined below) specified in the applicable Order Form (per SKU) (collectively and individually “Traffic Limits”). Such traffic, both actual and capacity limits, shall be viewable in the Acquia Cloud Platform Management Console. When the Platform CDN is enabled, the number of monthly views and unique visits will be reported from the CDN.

Acquia Inc. reserves the right to change the Products and Services Guide based on prevailing market practices and the evolution of our products. Changes will not result in a degradation in the level of services provided during the period for which fees for such services have been paid.

6. Acquia Cloud IDE

Acquia may make available, for Customer provisioning, a single IDE entitlement with each Acquia Cloud Platform subscription.
