MemSQL Helios Introduction
MemSQL Helios is the on-demand managed service version of MemSQL v7.1. It provides the same functionality, capabilities, ingest and query performance, scalability, and resiliency available through self-managed MemSQL clusters while handling all installation-, operation-, and management-related details.
MemSQL Helios is designed and architected to tolerate and recover from failures. To maintain each cluster’s high availability (HA), MemSQL Helios runs on a cloud-native, highly resilient infrastructure with high availability built-in.
MemSQL Helios high-level features include:
A fully-managed and resilient MemSQL database that can scale as needed
Cluster configuration, sizing, deployment, and monitoring via a graphical user interface (GUI)
Cloud-agnostic deployments on Amazon Web Services (AWS) and Google Cloud Platform (GCP), with Azure support slated for 2020, and others over time
Secure, with encryption of all data at rest, and TLS/SSL encryption for over-the-wire connections to the cluster
Automated infrastructure provisioning, configuration, elastic scaling, backups, hardware maintenance and failure management, and upgrades of MemSQL, operating system, and related system software

MemSQL Helios Maintenance
MemSQL Helios maintenance windows occur for all regions on the first and third Saturday of each month, at 12:00 PM EST / 5:00 PM UTC, and typically last for two (2) hours.
Email reminders for each upcoming maintenance window are sent to customers who have registered on the MemSQL Customer Portal and have an active MemSQL Helios cluster.
These maintenance windows allow improvements, bug fixes, and optimizations to be made to your clusters. On occasion, these updates may trigger a rolling online restart of your cluster. While MemSQL Helios clusters are redundant, and restarting nodes should not typically affect your workload, you may experience 2 - 5 minutes where DDL is unavailable during the restart as the Master Aggregator is updated.
