#Nexus package manager archive#

Any quick automation script can be put together and somebody has already done it in Jenkins world (or there is a plugin to do it).Nexus has been proven to be nimble, reliable and resilient solution for dependency management needs for years.Until we decide on neo4j enterprise edition, I wanted to have fault tolerance in place and needed a storage location.neo4j data folder was ~4mb, so I donвЂ™t want huge storage systems (Amazon S3 was an option I considered however Nexus can hold archives in Snapshots and Releases folder).Finally all of the above should be automated as much as possible.While restoring, I needed option to select which backup to restore.Decide where to store the folder (I wanted the backups to be accessible without restraints like enterprise firewalls etc.).

I had to come up with a naming scheme for backup folders everytime I archive the data folder.If I forgot the password, I would nuke вЂdbmsвЂ™ folder, and neo4j resets default credentials to neo4j/neo4j neo4j stores authentication information in $NEO4j_HOME/data/dbms (I was not particular about auth because it is still development phase).neo4j stores data in $NEO4J_HOME/data/ (and other files), so that makes it easier to separate out data.So after some digging around, I narrowed to the following salient options So as you can see, I wanted to make use of existing tools as much as possible and get to a point that application can make money and then go expand in investing on licensing etc. Not rely on heavy enterprise level centralized tools backup tools (yet).I did not want to invest in neo4j enterprise edition (yet).Restore it on-demand (Clustering was not yet required).Specific to neo4j, I wanted a way to backup and restore neo4j db as part of my development feedback loops. Since the application requirements keep changing and based on how we collect, analyse, transform data that feeds into application, the schema also changes based on feedback loops. Btw, the entire application is dockerized (docker-compose) and can be started with one command (including default data seeded). While it was very quick and easy to set up CI jobs in jenkins for UI and API layer, I started thinking what would make best sense for database layer. So I was working with an application recently, that was angular front end, expressjs api layer and backend neo4j graph database. I have been a big proponent of Automation and certain tools like Nexus, Jenkins have been part of my proposition to get started quickly and realize the benefits of CI/CD. Innovation is happening in bursts in every tool chain that we can think of towards the goal of more agility, self-service, faster distributed systems model. At the same time, leaps of optimization is happening in the way application development is moving away from monolithic towards micro-services. are paving the way for more independent and self-serviced capabilities in the hands of a developer. Tools like Docker, Jenkins, Nexus, Ansible etc. verticals (Think of it as decentralization of ownership in some ways). With Continuous Integration/Delivery and DevOps principles (coupled with 12-Factor app concepts), the ownership of application is moving more towards development teams aka. This is the still the reality in many organizations because of gap between Dev and Ops. And hence restoring configuration settings, application cache refreshes and dependencies that application/product requires happens in adhoc ways. It is generally left to the application development/operations team to figure out once database and network is switched over. Databases are generally a crucial piece of many applications built over the past few decades and focus was mainly on restoring database backups (that are taken at a regular interval).ДЄlso an enterprise team manages BCDR process horizontally and do NOT necessarily cater to needs and High Availability of вЂњApplicationsвЂќ. Traditionally failover to a new data center might mean вЂ“ Backup and restore databases, DNS mappings switched and bring the application services up as quickly as possible to ensure Business Continuity. Backup and Restore of databases is generally an operations domain and folks who might have worked in that space know how critical BCDR (Business Continuity Disaster Recovery) plans are вЂ“ planning for the worst.
