MongoDB Users: Get Ready for the AWS Reboot
Over the next few days, AWS will be issuing an emergency patch , and as part of this process they’ll rebooting a substantial number of EC2 instances. The maintenance starts tomorrow and will continue until the end of the month. To see if you’ll be impacted, AWS recommends you go to the “Events“ page on the EC2 console, which will list any pending instance reboots for your AWS account. For those of you who run MongoDB on EC2, you can easily distribute your replica set nodes across multiple availability zones to help ensure that your deployment withstands outages like these without suffering any application downtime. If you have a node in an AZ that gets rebooted, your replica set will automatically fail over to a node in a different AZ. No big deal. Here’s a (non-exhaustive) AWS-reboot-preparedness checklist: Backup. We always recommend you take regular backups. This weekend especially -- make sure you have a current backup of your data before the EC2 instances get rebooted. Availability Zones. As a general practice, we recommend that you deploy replica sets across multiple availability zones. In this case, you may want to proactively change your replica sets' primaries to nodes that will not be impacted by the reboot. And if your nodes aren’t spread across availability zones, we’d suggest that you make this change now so that you have a valid voting config when the instances get rebooted. Replica Set Review. Do a once over of your replica sets to ensure that, if any given availability zone is rebooted, you have enough voting members to continue normal database operations. Some common strategies include: Adding additional secondaries to the replica set Adding an arbiter to a replica set What to Expect. When AWS reboots the instances, you should expect to see failovers occur in your replica sets. A failover typically lasts no more than a few seconds, but while it’s in progress, writes will fail and reads on the primary will fail. Once the failover process has completed, normal operation should be restored. If for some reason normal operation is not restored, Production Support and MongoDB Enterprise customers should reach out to our support team; others should take advantage of our incredibly active community on Google Groups . Our support organization is on call to assist proactively in advance of the maintenance, or to respond in case of any incidents related to the reboot. And we’ve provisioned some extra folks this weekend just to be sure you have the help you need.
MongoDB at AWS re:Invent 2020
While 2020 has been a challenging year, it has also given rise to new levels of innovative collaboration and agile thinking. Where better to experience both than at AWS re:Invent 2020? At MongoDB, we’re excited to partner with AWS on this free, 3-week virtual event, providing unlimited access to hundreds of sessions led by Cloud experts. Although we’ll miss the grand, buzzing halls of the Venetian Hotel and the celebratory sounds of slot machines this year, it’s still important to approach AWS re:Invent with a focused plan. Think of this year’s event as an opportunity to curate your own perfectly tailored experience. Check out this page for details of our fresh new lineup of deep-dives, targeted jam sessions and — of course — the annual MongoDB late-night party. Here are some of the highlights. AWS Jam — "Excel isn't a database!" Imagine this: It's your first week in a new job, and the VP of sales has already given you an important data task. The good news? From the start of the year, all your current sales data has been stored in MongoDB Atlas — allowing operational and analytical workloads to run on the live data set. The not-so-good news? That wasn't always the case. For years before they switched, their database (well, ”database”) of choice was… Excel. Fortunately someone took the initiative to export that data in CSV format and store it in S3, but now the sales team needs your help to analyze that data — and they need it fast. In our “Excel isn’t a database!” Jam Session, you’ll test and upgrade your skills by connecting MongoDB Atlas Data Lake to CSV data that’s been languishing in an S3 bucket. Then you’ll run an aggregation to complete the challenge and claim points. Game on! This jam session will be available on-demand for the duration of AWS re:Invent Databases & S3: Auto-archiving Breakout Session Databases are built for fast access, but this can also make them resource-intensive. As data grows, you may want to optimize performance (or cost) by migrating old or infrequently used data into cheap object storage. But this presents its own problems: automating the archival process, ensuring data consistency during failures, and either querying two data stores separately or building a query federation system. In this talk, you’ll learn about how we approached these problems while building Online Archive and Federated Query features into MongoDB Atlas, lessons learned from the experience, and how you can do the same. MongoDB Late Nite That’s right: it’s a party! In the spirit of Vegas, MongoDB will be hosting an interactive late-night bash complete with throw-back entertainment at our virtual after-hours event.
