Licenses Cost in Topology Wizard
Starting with the current 5.7.7 PaaS release, the Estimated Cost section of the topology wizard was updated to consider and display details on the license price of the used stacks. Such a change allows providing better support of the recently added LiteSpeed Web Server and Web ADC servers. Herewith, the license price of any other software stack will be displayed in the topology wizard as well.
Also, some other adjustments were provided for the Estimated Cost section to make it cleaner and more intuitive. For example, free resources and savings highlighting, pay period switcher, additional explanatory notes.
Redeploy with Automatic Rollback from Snapshot
In the present 5.7.7 release, a new revision of the redeploy feature is introduced. Compared to the previous implementation, it implements multiple optimizations, which result in the following benefits:
- Due to the optimization of the flow, a copy of all the custom data won’t be created anymore. Thus, the operation speed is significantly enhanced, especially for big containers with lots of data.
- The redeploy actions are performed on the snapshot, which is discarded upon failure or merged upon success. Such a flow significantly boosts the reliability level of the container update operation.
- Multiple internal operations are omitted in the new algorithm, boosting the effectiveness and reliability (due to the lower number of failure points) of the redeploy operation even further.
As a result of these changes, the reliability level was considered sufficient to deprecate the redeploy backups option.
Welcome Tutorial Update
The platform welcome tutorial is a short presentation on the PaaS features and an interactive guide, which shows how to create an environment and deploy an application. It automatically starts on the very first login to the dashboard and can be manually called via the Help > Tutorial menu. In the current 5.7.7 PaaS release, a list of the central platform features for the tutorial was updated and provided with the renewed illustrations.
Supported OS Distributions Revision
In the present 5.7.7 PaaS release, a list of supported OS distributions for containers was actualized. Namely, the no-longer supported Fedora-based templates were removed. To run custom Docker containers based on the distributions that are not listed in the linked documentation, please contact us to negotiate the appropriate OS support.
Invoiced Period for Post Payment User Groups
Based on the particular service hosting provider settings, some customers can be charged based on the post payment approach. Namely, the platform can be used without restriction, but at the end of the month, an invoice for all the consumed resources will be sent. Starting with the present 5.7.7 PaaS release, such a charge additionally includes information on the billing period.
GlusterFS Mount Timeouts
Due to the recently implemented GlusterFS storage with Auto-Clustering, the mount timeout for the autofs daemon was set to three seconds to ensure quick failover. Herewith, such a value is too low when working with the regular Shared Storage and may cause errors. In the current 5.7.7 PaaS release, the algorithm for this timeout configuration was optimized to support both cases.
The new implementation sets the timeout in the /etc/autofs.conf file to 300 seconds by default. Then, in case a mount point from the GlusterFS node is created, the platform automatically switches the value to three seconds on the appropriate container.
Dashboard Headers Restyle
A new style was implemented for the headers of the different dashboard sections in the present 5.7.7 platform release. The updated view (e.g. elements and their separators color) is smoother and fits better with the latest dashboard visual scheme. Also, the styles for menus in tool panels were adjusted to ensure the correct display of the icons upon selecting a particular item.
Icons for Marketplace Solutions in Dashboard Search
The Dashboard Search is a powerful tool that allows locating the required elements quickly. Among other possibilities, it can look for the pre-packaged solutions from the platform Marketplace. Starting with the present 5.7.7 release, the packages discovered through the dashboard search are provided with their respective icons to improve applications' recognition.
