Amazon VPC lets you provision a logically isolated section of the Amazon Web Services (AWS) cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address ranges, creation of subnets, and configuration of route tables and network gateways. You can also create a hardware Virtual Private Network (VPN) connection between your corporate datacenter and your VPC and leverage the AWS cloud as an extension of your corporate datacenter.

You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your web servers that have access to the Internet, and place your backend systems such as databases or application servers in a private-facing subnet with no Internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to Amazon EC2 instances in each subnet.

VPC endpoints enable you to privately connect your VPC to services hosted on AWS without requiring an Internet gateway, a NAT device, VPN, or firewall proxies. Endpoints are horizontally scalable and highly available virtual devices that allow communication between instances in your VPC and AWS services. Amazon VPC offers two different types of endpoints: gateway type endpoints and interface type endpoints.

Gateway type endpoints are available only for AWS services including S3 and DynamoDB. These endpoints will add an entry to your route table you selected and route the traffic to the supported services through Amazon’s private network.

Interface type endpoints provide private connectivity to services powered by PrivateLink, being AWS services, your own services or SaaS solutions, and supports connectivity over Direct Connect. More AWS and SaaS solutions will be supported by these endpoints in the future. Please refer to VPC Pricing for the price of interface type endpoints.

There are two types of VPN connections that you can create: statically-routed VPN connections and dynamically-routed VPN connections. Customer gateway devices supporting statically-routed VPN connections must be able to:

• Establish IKE Security Association using Pre-Shared Keys
• Establish IPsec Security Associations in Tunnel mode
• Utilize the AES 128-bit or 256-bit encryption function
• Utilize the SHA-1 or SHA-2 (256) hashing function
• Utilize Diffie-Hellman (DH) Perfect Forward Secrecy in "Group 2" mode, or one of the additional DH groups we support
• Perform packet fragmentation prior to encryption

In addition to the above capabilities, devices supporting dynamically-routed VPN connections must be able to:

• Establish Border Gateway Protocol (BGP) peerings
• Bind tunnels to logical interfaces (route-based VPN)

Utilize IPsec Dead Peer Detection

Amazon S3 is a simple key-based object store. When you store data, you assign a unique object key that can later be used to retrieve the data. Keys can be any string, and they can be constructed to mimic hierarchical attributes. Alternatively, you can use S3 Object Tagging to organize your data across all of your S3 buckets and/or prefixes. 

Amazon RDS manages the work involved in setting up a relational database: from provisioning the infrastructure capacity you request to installing the database software. Once your database is up and running, Amazon RDS automates common administrative tasks such as performing backups and patching the software that powers your database. With optional Multi-AZ deployments, Amazon RDS also manages synchronous data replication across Availability Zones with automatic failover.

Since Amazon RDS provides native database access, you interact with the relational database software as you normally would. This means you're still responsible for managing the database settings that are specific to your application. You'll need to build the relational schema that best fits your use case and are responsible for any performance tuning to optimize your database for your application’s workflow.

By default, Amazon RDS chooses the optimal configuration parameters for your DB Instance taking into account the instance class and storage capacity. However, if you want to change them, you can do so using the AWS Management Console, the Amazon RDS APIs, or the AWS Command Line Interface. Please note that changing configuration parameters from recommended values can have unintended effects, ranging from degraded performance to system crashes, and should only be attempted by advanced users who wish to assume these risks.

Amazon S3 is secure by default. Upon creation, only the resource owners have access to Amazon S3 resources they create. Amazon S3 supports user authentication to control access to data. You can use access control mechanisms such as bucket policies and Access Control Lists (ACLs) to selectively grant permissions to users and groups of users. The Amazon S3 console highlights your publicly accessible buckets, indicates the source of public accessibility, and also warns you if changes to your bucket policies or bucket ACLs would make your bucket publicly accessible.

You can securely upload/download your data to Amazon S3 via SSL endpoints using the HTTPS protocol. If you need extra security you can use the Server-Side Encryption (SSE) option to encrypt data stored at rest. You can configure your Amazon S3 buckets to automatically encrypt objects before storing them if the incoming storage requests do not have any encryption information. Alternatively, you can use your own encryption libraries to encrypt data before storing it in Amazon S3.

DB instances are simple to create, using either the AWS Management Console, Amazon RDS APIs, or AWS Command Line Interface. To launch a DB instance using the AWS Management Console, click "RDS," then the Launch DB Instance button on the Instances tab. From there, you can specify the parameters for your DB instance including DB engine and version, license model, instance type, storage type and amount, and master user credentials.

You also have the ability to change your DB instance’s backup retention policy, preferred backup window, and scheduled maintenance window. Alternatively, you can create your DB instance using the CreateDBInstance API or create-db-instance command.

Taking control of your site with a content management system also has great advantages as far as your search engine rankings are concerned. All search engines like to see that websites are updated regularly and favor sites that alter their content on a regular basis. Our CMS platform provides search engine friendly web pages and also allows you to create your own page titles and meta tags used by the Search Engines for page rankings.

The CMS is browser-based and will work on both PC and Mac platforms using either Internet Explorer and Firefox. Keyboard shortcuts may vary between the two systems.

1) Reattach the link. If the page was renamed, the link might have been affected.

2) Confirm that the folder and content block do not contain special characters (such as ‘ “ # % & + / : ; < > ) in the title.

When in doubt, avoid using non-numerical or -alphabetical characters.

Requirements gathering is crucial, to make sure you buy on what you need, not on the shiny features that look good in the demonstration.

Another important factor is how easy the system is to use – most likely, the people you’d like to update the site won’t be that technically comfortable, so the best solution is one that has solid usability.

no. That is the biggest myth of CMSs. Most of the time, the real issues in content creation are around people and processes, not the technology. You need to manage your content creation like any other project – with a clear workflow and timetable, and enough people—with the right skills—to handle what you need to create. The CMS will help you get the content on to the site, but the much more difficult challenge is creating it. And computers don’t write very well.

The Web CMS does not require any special software or any technical knowledge to use. It is a web-based platform and can be accessed wherever you have an Internet connection and a web browser. The interface is very similar to Microsoft Word and does all of the HTML coding for you. You can concentrate on the content and not worry about how it will affect the page layout. It also automatically optimizes your site’s content for search, so that when someone searches for information on your site it is more likely to be found.
