Amazon Neptune
Amazon Neptune is a managed graph database product published by Amazon.com. It is used as a web service and is part of Amazon Web Services (AWS). It was announced on November 29, 2017.[1] Amazon Neptune supports popular graph models property graph and W3C's RDF, and their respective query languages Apache TinkerPop's Gremlin,[2] openCypher,[3] and SPARQL,[4] including other Amazon Web Services products. Amazon Neptune general availability (GA) was announced on May 30, 2018[5][6] and is currently available in 22 AWS regions. Neptune is HIPAA eligible.[7] On December 12, 2018, it was announced that Amazon Neptune was in-scope for Payment Card Industry Data Security Standard, and ISO compliance programs.[8] HistoryAmazon Neptune is based on Blazegraph. Amazon acquired the Blazegraph developers and the Blazegraph open source development was essentially stopped in April 2018.[9]
FeaturesExternal supportAmazon Neptune supports the open source Apache TinkerPop Gremlin[2] graph traversal language, openCypher query language[3] for property graphs, and the W3C standard Resource Description Framework's (RDF) SPARQL[4] query language. All three can be used on the same Neptune instance, and allows the user to build queries to navigate highly connected data sets and provides high performance for both graph models. Neptune also uses other AWS product features such as those of Amazon S3, Amazon EC2 and Amazon CloudWatch.[11] SecurityAll Amazon Neptune database clusters are created and stored in an Amazon Virtual Private Cloud (VPC), which allows the user to isolate their database in their own private network. Using Neptune's VPC configuration, the user can configure firewall settings to their needs in order to control network access to database instances. Amazon Neptune is integrated with AWS Identity and Access Management (IAM), which allows the user to create AWS IAM groups and control the actions that the groups and other AWS IAM users can do. Neptune allows the user to encrypt databases using keys created through AWS Key Management Service (KMS). A database instance running with Neptune Encryption, encrypts all of the stored data, backups, snapshots and replicas in the same cluster. Amazon Neptune allows the user to use HTTPS to encrypt data during its transfer to and from clients or Neptune service endpoints using Transport Layer Security (TLS).[12] StorageThe data is stored in a cluster volume, a virtual volume utilizing SSD drives. These sizes of these volumes are dynamic, they increase depending how much data is stored in the database, with a maximum of 64 TB. The Amazon Neptune SLA policy is designed to offer a monthly uptime percentage greater that of 99.9%, increasing database performance and availability by integrating the engine with a virtual storage based on SSD drives, that are specially made for database workloads. Neptune maintains copies of the user's data in multiple Availability Zones. In case of failures, Neptune automatically detects any failed segments in a disk volume and repairs them.[13] AvailabilityNeptune is now generally available in the US East (N. Virginia), US East (Ohio), US West (Oregon), US West (N. California), Canada (Central),[14] AWS GovCloud (US-West),[15] AWS GovCloud (US-East),[16] Europe (Ireland), Europe (London),[17] Europe (Frankfurt),[18] Europe (Stockholm),[19] Europe (Paris),[20] South America (São Paulo), Asia Pacific (Singapore),[21] Asia Pacific (Sydney),[22] Asia Pacific (Tokyo),[23] Asia Pacific (Mumbai),[24] Asia Pacific (Seoul),[25] Asia Pacific (Hong Kong), China (Ningxia), China (Beijing), Operated by NWCD,[26] and Middle-East (Bahrain)[27] AWS regions. PricingPricing is determined by AWS regions, with each region having different prices for the available services. On-Demand Instance Pricing lets the user pay only for what instance they use by the hour instead of a fixed sum. The price also differs depending on the instance class. Similarly, the user only pays for the storage consumed by the database, with no payments in advance. The price is based on the storage rate and I/O rate, which are billed in GB per month and per million request increments respectively. This pricing model is beneficial to short-term and small-scale projects and is available in all AWS regions. The price for backup storage is also billed in per GB-month increments albeit at different rates. Data Transfer is priced in per GB increments, the amount depends on whether the data is transferred in or out of Amazon Neptune and how much data is transferred per month (TB per Month).[28] ApplicationOn September 12, 2018, it was announced that Neptune achieved HIPAA eligibility[7] enabling it to process data sets containing protected health information (PHI). On December 12, 2018, it was announced that Amazon Neptune was in-scope for Payment Card Industry Data Security Standard, ISO 9001, ISO 27001, ISO 27017, and ISO 27018 compliance programs.[8] The user can use Amazon Neptune in applications that are subject to PCI compliance or require ISO certification.[29] On May 17, 2019, it was announced that Neptune achieved SSAE 16 eligibility [30] Neptune powers graph use cases such as recommendation engines, fraud detection, knowledge graphs, drug discovery, network security, and social networking.[31] Notable usersSome notable customers of Amazon Neptune include, Samsung Electronics, Pearson, Intuit, Siemens, AstraZeneca, FINRA, LifeOmic, Blackfynn, and Amazon Alexa[32] See alsoReferences
