What is meant by sharding?
Sharding is a method for distributing a single dataset across multiple databases, which can then be stored on multiple machines. This allows for larger datasets to be split in smaller chunks and stored in multiple data nodes, increasing the total storage capacity of the system.
Is sharding vertical or horizontal?
Sharding is also referred as horizontal partitioning. The distinction of horizontal vs vertical comes from the traditional tabular view of a database.
Why do I need to partition my database into different filegroups?
A database object that maps the partitions of a partition function to a set of filegroups. The primary reason for placing your partitions on separate filegroups is to make sure that you can independently perform backup operations on partitions. This is because you can perform backups on individual filegroups.

SQL Server scheduler can help with splitting a new partition range and adding new filegroups as it is required for the partition functions and schemes.
Are there index rebuilds for partitions in SQL Server?
