AppSync는 AWS에서 제공하는 Managed GraphQL 서비스이다. 즉, 서버리스의 형태로 GraphQL 백엔드를 개발할 수 있는 서비스이다. AppSyn 를 사용하지 않고도 AWS Lambda 등을 활용하여 GraphQL 백엔드를 구축하는 것이 가능했으나, 이 경우에는 Lambda 메모리 사이즈, 콜드스타트, DataSource와의 통신, 인증된 유저 토큰 처리 등등 고민해야하고 직접 개발해야하는 것들이 더 많았다. 그러나 AppSync 를 활용하면 GraphQL 스키마를 작성하고 스키마의 각각의 필드에 대한 resolvers 를 작성하는 것만으로도 GraphQL 엔드포인트를 생성할 수 있다. Resolver AppSync에서는 resolver를 VTL이라는 자바 기반 템플릿 언어으로 작성한다.

AWS DataSync is a secure, online service that automates and accelerates moving data between on premises and AWS Storage services. DataSync can copy data between belows: Network File System (NFS) Server Message Block (SMB) Hadoop Distributed File Systems (HDFS) self-managed object storage AWS Snowcone Amazon Simple Storage Service (Amazon S3) buckets Amazon Elastic File System (Amazon EFS) file sy

Elastic Block Store (EBS) An Amazon EBS volume is a durable, block-level storage device that you can attach to a single EC2 instance. You can think of EBS as a cloud-based virtual hard dist. You can use EBS volumes as primary storage for data that requires frequent updates, such as the system drive for an instance or storage for a database application. You can also use them for throughput-intensiv

The main difference between gp2 and gp3, however, is gp3’s decoupling of IOPS, throughput, and volume size. This flexibility – the ability to configure each piece independently – is where the savings come in. On the opposite end of the spectrum, gp2 is quite inflexible. Sizing a gp2 volume involves considering both the storage and throughput requirements simultaneously, as volume performance h

EBS vs Instance Store

Characteristics Instance Store: Ephemeral storage: Data stored in Instance Store volumes is tied to the lifecycle of the EC2 instance. If the instance is stopped, terminated, or experiences a failure, the data is lost. High I/O performance: Instance Store provides high I/O performance and low latency since the storage is directly attached to the physical host of the EC2 instance. Instance-depen

EFS provides a simple and fully managed elastic NFS file system for use within AWS. EFS automatically and instantly scales you file system storage capacity up or down as you add or remove files without disrupting your application. In EFS, storage capacity is elastic (grows and shrinks automatically) and its size changes based on adding or removing files. While EBS mounts on EBS volume to one

Amazon FSx for windows File Server provides a fully managed native Microsoft File System. With FSx for Windows, you can easily move your Windows-based applications that require file storage in AWS. It is built on Windows Server and exists solely for Microsoft-based applications so if you need SMB-based file storage then choose FSx. FSx for Windows also permits connectivity between on-premise

S3 provides developers and IT teams with secure, durable, and highly-scalable object storage. Object storage, as opposed to block storage, is a general term that refers to data composed of three things: the data that you want to store an expandable amount of metadata a unique identifier so that the data can be retrieved This makes it a perfect candidate to host files or directories and a poor ca

S3 Glacier Vault Lock

S3 Glacier Vault Lock helps you to easily deploy and enforce compliance controls for individual S3 Glacier vaults with a Valut Lock policy. You can specify controls such as “write once read many” (WORM) in a Vault Lock policy and lock the policy from future edits. After a Vault Lock policy is locked, the policy can no longer be changed or deleted. S3 Glacier enforces the controls set in

Snowcone is the smallest AWS Snow family data transfer device. It can delivery 8TB Storage. Send data offline via device delivery or to AWS via AWS DataSync over the Internet Snowball Snowball is a giant physical disk that is used for migrating high quantities of data into AWS. It is a peta-byte scale data transport solution. Using a large disk like Snowball helps to circumvent common large scale

Storage Gateway

Storage Gateway is a service that connects on-premise environments with cloud-based storage in order to seamlessly and securely intergrate an on-prem application with a cloud storage backend. Storage Gateway comes in three flavors: File Gateway, Volume Gateway and Tape Gateway. Storage Gateway Key Details: The Storage Gateway service can either be a physical device or a VM image downloaded onto
