Explicit Allow : Allows access to a particular resource so long as there is not an associated Explicit Deny. Access instead must be granted. 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:.
This makes it a perfect candidate to host files or directories and a poor candidate to host databases or operating systems. The following table highlights key differences between object and block storage:. Data uploaded into S3 is spread across multiple files and facilities.
The files uploaded into S3 have an upper-bound of 5TB per file and the number of files that can be uploaded is virtually limitless. S3 buckets, which contain all files, are named in a universal namespace so uniqueness is required. All successful uploads will return an HTTP response. Objects regular files or directories are stored in S3 with a key, value, version ID, and metadata. They can also contain torrents and sub resources for access control lists which are basically permissions for the object itself.
The data consistency model for S3 ensures immediate read access for new objects after the initial PUT requests. These new objects are introduced into AWS for the first time and thus do not need to be updated anywhere so they are available immediately. Amazon guarantees Bucket policies secure data at the bucket level while access control lists secure data at the more granular object level. S3 can be configured to create access logs which can be shipped into another bucket in the current account or even a separate account all together.
This makes it easy to monitor who accesses what inside S3. S3 is a great candidate for static website hosting. When you enable static website hosting for S3 you need both an index. Static website hosting creates a website endpoint that can be accessed via the internet. When you upload new files and have versioning enabled, they will not inherit the properties of the previous version. S3 Standard - Data in this class is stored redundantly across multiple devices in multiple facilities and is designed to withstand the failure of 2 concurrent data centers.
S3 Infrequently Accessed IA - For data that is needed less often, but when it is needed the data should be available quickly. The storage fee is cheaper, but you are charged for retrieval. This is even cheaper because of the lack of HA. It does this without operational overhead or performance impact. S3 Glacier - low-cost storage class for data archiving.
Retrieval times range from minutes to hours. There are differing retrieval methods depending on how acceptable the default retrieval times are for you:. The Expedited duration listed above could possibly be longer during rare situations of unusually high demand across all of AWS. If it is absolutely critical to have quick access to your Glacier data under all circumstances, you must purchase Provisioned Capacity.
Provisioned Capacity guarentees that Expedited retrievals always work within the time constraints of 1 to 5 minutes. S3 Deep Glacier - The lowest cost S3 storage where retrieval can take 12 hours. Encryption In Transit : When the traffic passing between one endpoint to another is indecipherable.
Encryption At Rest : When the immobile data sitting inside S3 is encrypted. Encryption at rest can be done either on the server-side or the client-side. The server-side is when S3 encrypts your data as it is being written to disk and decrypts it when you access it. The client-side is when you personally encrypt the object on your own and then upload it into S3 afterwards. The Amazon S3 notification feature enables you to receive and send notifications when certain events happen in your bucket.
To enable notifications, you must first configure the events you want Amazon S3 to publish new object added, old object deleted, etc. Amazon S3 supports the following destinations where it can publish events:. All S3 objects are private by default, however the object owner of a private bucket with private objects can optionally share those objects with without having to change the permissions of the bucket to be public.
This is done by creating a pre-signed URL. Using your own security credentials, you can grant time-limited permission to download or view your private S3 objects. The pre-signed URLs are valid only for the specified duration and anyone who receives the pre-signed URL within that duration can then access the object.
It serves up cached content and assets for the increased global performance of your application. The main components of CloudFront are the edge locations cache endpoints , the origin original source of truth to be cached such as an EC2 instance, an S3 bucket, an Elastic Load Balancer or a Route 53 config , and the distribution the arrangement of edge locations from the origin or basically the network itself.
More info on CloudFront's features. 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 data transfer problems such as high network costs, long transfer times, and security concerns. Snowballs are extremely secure by design and once the data transfer is complete, the snowballs are wiped clean of your data. Storage Gateway is a service that connects on-premise environments with cloud-based storage in order to seamlessly and securely integrate an on-prem application with a cloud storage backend.
Volume Gateway's Stored Volumes let you store data locally on-prem and backs the data up to AWS as a secondary data source. Stored Volumes allow low-latency access to entire datasets, while providing high availability over a hybrid cloud solution. Further, you can mount Stored Volumes on application infrastructure as iSCSI drives so when data is written to these volumes, the data is both written onto the on-prem hardware and asynchronously backed up as snapshots in AWS EBS or S3.
Volume Gateway's Cached Volumes differ as they do not store the entire dataset locally like Stored Volumes. Instead, AWS is used as the primary data source and the local hardware is used as a caching layer. Only the most frequently used components are retained onto the on-prem infrastructure while the remaining data is served from AWS. This minimizes the need to scale on-prem infrastructure while still maintaining low-latency access to the most referenced data.
EC2 spins up resizable server instances that can scale up and down quickly. An instance is a virtual server in the cloud. With Amazon EC2, you can set up and configure the operating system and applications that run on your instance. Its configuration at launch is a live copy of the Amazon Machine Image AMI that you specify when you launched the instance. EC2 has an extremely reduced time frame for provisioning and booting new instances and EC2 ensures that you pay as you go, pay for what you use, pay less as you use more, and pay even less when you reserve capacity.
When it is stopped, you are only charged for EBS storage. The following table highlights the many instance states that a VM can be in at a given time. Note : Reserved Instances that are terminated are billed until the end of their term. Placement groups balance the tradeoff between risk tolerance and network performance when it comes to your fleet of EC2 instances.
The more you care about risk, the more isolated you want your instances to be from each other. The more you care about performance, the more conjoined you want your instances to be with each other. You can move an existing instance into a placement group guaranteed that it is in a stopped state. You can also take a snapshot of the existing instance, convert it into an AMI, and launch it into the placement group where you desire it to be. You can think of EBS as a cloud-based virtual hard disk.
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-intensive applications that perform continuous disk scans. An elastic network interface is a networking component that represents a virtual network card.
When you provision a new instance, there will be an ENI attached automatically and you can create and configure additional network interfaces if desired. When you move a network interface from one instance to another, network traffic is redirected to the new instance. They act as a virtual firewall for your instances to control inbound and outbound traffic.
When you launch an instance in a VPC, you can assign up to five security groups to the instance and security groups act at the instance level, not the subnet level. AWS WAF gives you control over how traffic reaches your applications by enabling you to create security rules that block common attack patterns, such as SQL injection or cross-site scripting, and rules that filter out specific traffic patterns that you can define.
Amazon CloudWatch is a monitoring and observability service. You can find us in the WordPress support forum for this plugin. It helps greatly if you can include the backup log and as much other information as possible in your report, for example, the PHP version, your website, the error description, how you got to the page that caused it, any other relevant plugins you have installed, plus any other information that might be of use.
To find the backup log: there are links to download the logs on the UpdraftPlus settings page- or you may be emailed it. This problem is probably caused by your account being starved of resources by your cheap web host provider.
